Equipment - The Black Tsunami (pictures)

A bit bright, it seems, but on the camera it seemed fine. I didn't bother trying to edit the pictures. I'm putting them here as much for reference as anything else.

Some updates to the bike - the ISM saddle, it has a wireless SRM now, a not-visible-in-the-picture PC7 (wireless SRM head).

There's a rear camera on it, Shimano CM-1000. I'm not 100% on it yet but it seems to reliably turn on and record, so there's that.

I've had the Exustar pedals for a while now, although I don't remember if I have pictures of them on the bike from before.

Only notable thing is the front derailleur mount broke, probably today. The derailleur wouldn't shift into the big ring so I just manually placed the chain there and left it for the ride (I rode outside!).

With the training clinchers on them.

Equipment - Bike Weight (Red Tsunami)

After reading some stuff about bike weights online I got curious about my own bike's weight. For the EVEN Hotel Fun Ride I brought a bunch of bike mechanic stuff to the hotel that I don't normally touch. This included packing the bike tool box (which has my big digital scale in it, meaning the scale for weighing stuff over 1000 grams) as well as the repair stand (which is perfect for holding the previously mentioned scale). After the ride I unloaded the stuff into the garage and it hasn't moved since. My race wheels sit there as well.

I realized that I had everything I needed to weigh my bike in its various iterations.

So I did.

My main focus was to see the delta in the weights for the wheels. I mean, okay, the ultimate weight is nice to see, but I wanted to see if there was any objective data to back up my very subjective opinions and such. I didn't put the SRM PCV (computer head) on the bike, it's about the only thing missing in terms of "always on the bike". The tail lights (I use two), saddle bag full of stuff, and pump, they go on for training rides but not for races. Bottle - since I usually ditch my bottle before the finish I figured keeping it off was fine.

My bike, after the Nutmeg State Games 2014. Stinger 7/9 wheels.
Weight = 16.2 lbs without bottle and SRM head.

The results below:

Red Tsunami bike, no pump, no bottle, no SRM head, no tail lights, no saddle bag with stuff in it. I train on the bike with the Jets right now.

Bike with Jet 6 front and Jet 9 rear wheels: 8.62 kg, 18.98 lbs.

Note that all the HED wheels, except the Stinger 7/9 combo, use the same model hubs and spokes. Even the Stinger 7/9 use very similar weight hubs. Therefore the majority of the weight differences are in the tire/tubes, rims, cassette, and a minor difference due to small variations in spoke count.

On the clinchers I'm using Maxxis ReFuse training tires, Bontrager tubes, and Velox rim strips. On the tubulars I have either Vittoria EVO tires (one of them is a Tech rain tire and the rest are regular CXs) or the Bontrager XXXLite tires. Weights for the tubular tires are virtually identical.

2010 HED Jet aero clinchers (with stock HED front skewer and trainer rear skewer)

Jet 6 front wheel, 1.71 kg / 3.77 lbs
Jet 9 rear wheel, 1.97 kg / 4.33 lbs (with 11-25 steel Campy Centaur? cassette)

2010 HED Bastogne clinchers (with stock HED front skewer and trainer rear skewer)

Bastogne front wheel, 1.16 kg / 2.55 lbs
Bastogne rear wheel, 1.62 kg / 3.57 lbs (with 11-25 steel Miche or BBB cassette)

2011-2012 HED Stinger 7/9 aero tubulars (with stock HED skewers)

Stinger 7 front wheel, 1.10 kg / 2.42 lbs
Stinger 9 rear wheel, 1.31 kg / 2.88 lbs (with 11-23 steel Miche or BBB cassette)

2010 HED Stinger 6 aero tubulars  (with stock HED skewers)

Stinger 6 front wheel, 0.95 kg / 2.09 lbs
Stinger 6 rear wheel, 1.31 kg / 2.88 lbs (with 11-21 ti/steel Campy Record cassette)

Bike weights with clinchers

With Bastognes, 7.72 kg / 17.0 lbs
With Jets, 8.62 kg / 18.98 lbs

Bike weights with tubulars

With the Stinger 7/9 setup weighs 7.35 kg or 16.19 lbs.
With the Stinger 6 wheels weighs 7.20 kg or 15.85 lbs.

Thoughts

The first thing is that I thought my bike was much heavier when set up for training. 19 pounds is not a lot for a bike, and to me the bike feels like a tank with the Jet wheels fitted. If I were to guess I'd have said my bike weighed 20-22 pounds so to have a 19 pound bike is pretty surprising. When I started racing a 19 pound bike was super light, and 20-21 pounds was about normal for a race bike. I've taken spins on 12 pound bikes in parking lots and they feel like they're made from styrofoam, they're so light, and my bike is nowhere near that.

Second I knew the Jets were heavy but to weigh about 8 pounds for the pair of wheels (with tires etc) is pretty substantial. The Jets give away about 1.5 kg or over THREE pounds to my tubulars. The front clincher wheels, which are identically set up in terms of hub/spokes/tire/tube/rimstrip, are about half a kilo apart so that's a full pound or more in just the rim. Let me repeat that in bold. The rims make for a full pound difference! The only difference between the two front wheels is the rim so that's where the weight is, directly in the rim area. This is why the wheels feel so hard to spin up, the rims weigh twice as much. They are more aero but I use so much energy getting them up to speed that I'm pretty much exploded by the time I'm able to substantially use the aero benefits.

Third, I was shocked to see that the Stinger 9 and the Stinger 6 rear wheels weigh the same. The 9 even has a heavier cassette and a marginally heavier tire. To see that it weighed the same means that basically it'll be my standard rear racing wheel. The 6 no longer has a function. It's not lighter, a tall rear wheel is always usable, and I'll have a higher top speed for a given power in a sprint. Since the Stinger 6 rim is cracked I may build it out as another 9.

The final thought is that I figured my bike was heavier in general. To be so close to the UCI minimum weight of 6.8 kg / 15 lbs surprised me. My Cannondale 2.8 was, at best, about 17 pounds with extremely light tubular wheels (280g rims, 28H, hubs similar to modern day hubs). This was on a spring-type scale (a fish scale sold through a bike distributor) so the accuracy was questionable at best, but it was a pretty light bike. The Cannondale SystemSix, with the Reynolds tubular DV46 wheels, came in at about 15.5 pounds, on the same digital scale I used to record all the above weights. The Tsunami only gives away a third of a pound compared to the very sweet System Six. It's virtually the same build kit so it's the wheels, the saddle (my carbon railed SLR is light), the fork (my current ENVE 2.0 is light), and the (probably heavier) Steelman stem and FSA Wing bar that are different.

Going Forward

I suppose I could cut some weight off by swapping cassettes between the Stinger 6 and Stinger 9 - the 11-23 ti/steel cassette is noticeably lighter than the 11-23 steel cassette. However the overall result wouldn't be significant. I wouldn't be able to tell the difference between the two, separated by 50 or whatever grams, or 0.05 kg.

I don't have any weight weenie parts per se. Thomson seatpost (the regular one), FSA Wing Compact bar (aluminum), Campy Skeleton brakes (Athena? I bought them used), Crank Bros headset, Specialized Rib Cage bottle cage. I even left two Planet Bike blinky light mounts on, and the bike had the SRM mount (but not the actual computer head).

The light stuff I have on the bike includes the ENVE 2.0 fork, the carbon railed SLR saddle, and… I think that's it. Both are long term items, not wear items. I plan on having them for a long time. I bought some lighter weight tubes (60g vs 90g) but, again, realistically I'm not going to notice that as much as if I move from one wheel set to another. Plus they're thinner and slightly less durable so I'll stick with training on regular tubes for now.

Steelman Bikes stem, it's not light. 257.4 grams unpainted, so 0.57 pounds by itself. I think a typical stem is in the 100-120g range. That's a substantial difference relatively speaking, to double the weight of a part. However fit is absolutely critical so I can't nitpick the weight of the stem.

Tsunami frame, alone, is about 1300g with paint, binder clamp, and barrel adjusters. Unpainted it was 1210g. My frame and fork should weight in the 1650g range (with a 350-ish gram fork). The Cannondale was supposed to be 1150g for the 56 cm so a bit less for the 52 cm I rode. Again fit is first so a little bit of weight is a normal sacrifice for a custom fit, sub-$800 frame.

I do have a light crankset, the Cannondale SI SRM, which is about 675g total, with bottom bracket. I think I've weighed it but I don't know if I ever put the pictures up, and looking through about 20k pictures doesn't appeal to me right now. A typical crankset (Campy Record aluminum with Record BB) will weight 900g or more.

However, for basically no carbon except the rims and the saddle rails, the bike isn't heavy at all.

Realistically it would be easy to drop a little weight in the training wheels, but that's not my goal. In fact I want to keep the bike heavy for training.

For racing I might be able to shed a few grams here and there. However, with my own body weight something like 9000 g / 20 pounds higher than in 2010, spending money to save 40 or 50 grams seems ludicrous. Therefore I'm not going to do anything to the bike.

Racing - 2014 New Britain Crit, M45 and Cat 3s

My bike, resting.

Podium Ice bottle, no longer a rarity with the new version coming out soon.

I think I have an 11-23 for the cassette.
Nokon housing.

My one light thing - a carbon railed SLR.

Thanks to teammate Heavy D, who grabbed my camera after the M45 race, I have some pictures of me on the bike. This is unusual since normally I'm the one taking pictures with it. Coincidentally my helmet cam failed to stay powered on so I don't have any video. Therefore the pictures Heavy D took are the ones I'll use to narrate the Cat 3 race.

At the start.

I preach about long finger gloves. They save your finger tips on the off chance that you hit the deck and slide on your fingers. It doesn't happen all the time but it's happened to me. I'd rather not repeat that experience so I wear long finger gloves all the time, even training rides in the summer. I sometimes forget them and since it's not a critical thing like a helmet I'll still go for a ride. However you'll almost always find me wearing long finger gloves.

I use a RoadID. I have a heart thing so if I'm unconscious and someone hooks up an EKG thing to me, it'll look like I'm having a heart attack. Since I don't want anyone to do anything to me to try and "fix" my heart, I wear the RoadID. I carry a copy of my EKG in my wallet as well, per my doctor's recommendation.

They've been a generous and steady supporter of local bike racing for literally decades.

Stickers.
I'm starting again with this bike. Note Outdoor Sports Center, sponsor of the Bethel Spring Series.

I race for that club.

M45+

First the M45+. I don't have pictures at all so it'll all be words. I lined up with no warm up, per my Strava. I was running a bit slower than I thought and I didn't feel the need to warm up anyway.

We started off fine, some attacks early on. We had pretty strong winds, with a very strong cross-headwind on the main stretch. I expected a break to go because of that so I figured that I'd go after any bigger move that started rolling away from the field.

One big move went (I think) but I figured it would come back. It did.

Then another, bigger move went. This had a good 10 riders or so, and there were a number of break member teammates in the field. A few of us had missed the move but the chase seemed a bit half hearted. I made a dig, accelerated a bit more than I wanted, and decided to follow through with it. I rolled up to the break within half a lap, connecting on the backstretch. I felt okay, not totally redlined, and I figured that if the break kept at this pace I'd be okay.

Behind me the field seemed strung out but not any more motivated than before. In front of me the break started to splinter, with the front half separating from the rear. Over the top of the hill my chain inexplicably dropped off the big ring, not quite going into the small ring. I must have been in the 53x23, meaning in the big-big, and either stutter pedaled or something to unhook the chain.

I lost a few feet getting the chain back up to the big ring, looked back, and sat up.

By the time we hit the main stretch the field had caught the break. I was definitely working harder than not but I didn't feel in trouble. The field, already a bit stressed, split again, I think under the impetus of some of the stronger riders.

Unbeknownst to me there was an ex-pro in the field, Kurt Begeman, who used to be the resident pro at the velodrome in New Hampshire. Had I known he was in the field I'd have kept track of him, but I didn't so I didn't.

From my tail gunning position I thought the break had come back but it had actually increased its lead so quickly it was around my reference corner (the last one). When I looked it wasn't there so I mentally relaxed. A few laps later I saw that they were actually really far in front, a good 30 seconds or so.

I made another dig, hoping to bring some guys with me, but no luck. Everyone let me blow up out there and a lap later I came back.

Going into the final lap I figured I'd go for the sprint (of course). I actually debated whether I should just sit up and save my legs for the 3s. Ultimately I decided to sprint because I couldn't possibly know what would happen in the 3s. I might crash or flat or get shelled or something because that's what bike racing is all about.

Carpe Diem, right?

Seize the Day, or seize the moment.

An ex-Cat 2 (or 1?), Martin, went really early, gapping off the field I think going clear just before the last turn. My friend (and long time Bethel Spring Series helper) David B sat on his wheel. If they won, so be it, I didn't want to chase them myself.

Another guy followed and I immediately jumped on his wheel. We rounded the last turn and I looked up at Martin and David. They were probably 15-20 meters ahead, a closable gap in the sprint. I knew the powerful headwind would really slow my sprint so I went as soon as I thought I could get to the line.

I thought I'd left it late as it was a big gap to Martin and David, but I think the wind really shattered them. I got past both of them to get 15th. In the Tour that might be good but here at New Britain, not so much.

I'd used up a bunch of water, the day was getting warmer, and I had another race in 2 hours. I realized that I'd made an error in my race supplies - I should have brought more water and some food. Instead I ate a bar, drank some of the precious ice water, and waited. Junior wanted to play and stuff so we played and stuff. Heavy D collected my camera to take pictures of the Cat 4 race. I was hot.

Cat 3

Strava here.

Unusually I'm near the front. Cat 3s.

I didn't intend to line up near the front, I just rolled up whenever and there were more people than I expected in the field. Naturally since I lined up with at least one rider behind me I screwed up my clip in. I apologized to the rider that had to pass me as I clipped in and we were under way.

The Stingers in action.

My teammate Heavy D took control of my camera, with the 55-200 zoom, and snapped away. He'd try to cheer us on while taking pictures. You can tell when he was cheering because there's a whole lot of pavement and grass. The laps where he wasn't cheering there's a bunch of cyclists in the frame. The above picture is one of the in-between ones.

This is interesting. Note the gaps between wheels and such.
Cat 3 race so we're all reasonably experienced.

Keep in mind that the wind really socks us hard from the front left after this turn. Tactically speaking then it would make perfect sense to be shielded to the wind side, i.e. to the front left. This means riders should be exiting the turn behind and to the right of the rider in front of them, giving them optimal protection immediately.

The picture above doesn't show much of that.

Now note the tight formation, center screen.

The crafty guys at the back of the field are a bit better. You can see we're in our own mini-echelon. The rider in orange, the rider  with the white helmet, they're in the wind for no reason whatsoever, using enormous amounts of energy and gaining nothing.

Another picture of the tight formation.

We're overlapped to the right because the wind is hitting us from the left. The two riders in front of me have multiple national titles between them and both are former Olympians for other countries. I'm not so good but at least I know what's up.

A shot of the "kick over the top" pedal stroke I have.
Here the wind wasn't as powerful so being close wasn't as important.

I don't have long legs, as evident in this picture, but I run 175mm cranks. It just works better for me, now that I've lost a lot of leg speed. 25 years ago I was using 167.5mm cranks, and in about 1995 I started using 170s. Over the 2003-2004 winter I started using 175s. I thought 170s would be faster so I tried to go back to them in 2008 and then again in 2011. I tried for most of a season each time, starting sometime in the prior fall (typically Oct/Nov to July/Aug). Both times I went back to the 175s and immediately had better results. It wasn't the power, which I found didn't change much at all, it was how that power translated into fatigue and results. The 175s just work better for me.

Although technically I was okay sitting at this part of the course, at the top of the hill, I needed to stretch my legs out a bit. As the second race of the day my legs were getting fatigued. I also ran out of water so that didn't help on this hot and humid day.

Coasting and stretching. I'm pressing my right thigh against the left side of the saddle.

I'm coasting here, trying to stretch my legs out a bit. The standing at the top of the hill helped but I still needed to do something, my legs felt really blocked and fatigued.

Last wheel in the field, suffering.

I'm last wheel here and not very close to the next rider. This was in the first curve and the trees break up the wind. Still, though, I should be a bit closer.

This picture, more than the earlier ones, shows that I really need to lose weight. No muscle definition - my body fat is in the 25% range, give or take. I'm realistically 20 pounds heavier than I could be, than I was in 2010, and in 2010 I still wasn't really cut/defined. Someone calculated my lean body mass is in the 130s so 10% body fat would put me in the 140s. It'd be nice to be in the 150s again.

More suffering.

We're exiting the tree area I think and I'm closer to the wheels. However I'm still suffering, still at my limit.

My ContourHD didn't work in the Masters race so I removed it for the Cat 3s. You can see the mount on the helmet. No camera though.

Also you'll note that I have no SRM. I forgot it at home.

I ran out of water pretty early in the race, saving a few sips "just in case". At about 10 to go I started thinking about stopping. It was hot, there was a break up the road, and I wasn't recovering at all.

Then, at 8 laps to go, the sun disappeared behind some clouds. It was still bright, mind you, but the sun wasn't beating down on us. I could feel my body start to shed some of that excess heat, finally getting ahead of the recover curve. I hoped that the sun would stay hidden, and it did, at least until it was too late to cook me again.

Sprinting for 13th. I was 12th when I sat up, my wheel just in front of that tall rider to my right.
I would have sworn up and down that there were 20 riders ahead of me.

I was so far back going into the sprint that I really didn't feel like sprinting. On the other hand I'd worked so hard just to get to the finish that I decided to give it a go, even as I saw riders 10-20 feet in front of me sitting up.

I didn't have a good jump and my legs were twinging even as I jumped but I kept going. The pedals turned really slowly, no 105 rpm sprint like last time. I know when I'm not sprinting well because my butt gets lower and lower, and that's what was happening in this sprint. At some point I started to pass a tall, skinny rider, the archetypal non-sprinter, and my legs told me I was done.

I sat up and the other guy passed me back. I saw three guys at the line within passing distance, including the tall guy, but at best I might have gotten past those. No way I could have caught anyone further up.

Ends up I was 13th so if I'd done a reasonable sprint I probably could have gotten 10th. No better though, especially based on the fact that I really couldn't move up in the last lap. If I was so blown that I couldn't move up then I was really on edge in the race itself.

The good thing is that I finished the races disappointed in the Masters to have missed the break and disappointed in the 3s to have screwed up the finish. Previously I'd have been psyched just to finish. I'd bumped up my training in June to 16 hours, double that of May, and more than April and May combined. In July I've already done 10 hours and we're only halfway through the month.

Note the last day's bar in July is taller than any day except that tall day in late January.

Incredibly, with the EVEN Hotel recon ride later that day, this would be the longest day of the year for me since January, and in fact it was the second longest day of the year on the bike period.

With that my next big day is the EVEN Hotel Fun Ride coming up on Thursday morning.

No Tuesday Night CCAP Race tonight due to the thunder, lightning, flood watch, and all that. I even got an emergency broadcast message on my phone. Tomorrow I'm heading down to the EVEN Hotel thing. This weekend is booked solid with family stuff. Next Tuesday there's no race - I may try to figure out a way to do the Wednesday Night race at Ninigret, which is withering on the vine. Hm, they're off next week also. I guess my next race will be Limerock on the 27th? M40 and Cat 3.

Well, I guess that's okay. One way of looking at it is that I'll have time to train a bit. Imagine that.

Racing - 2014 Circuit Francis J Clarke

Today for some reason I was a bit more relaxed than on other weeks. I think part of it was the staff - the race was going really smoothly and I felt like things were under control. No craziness, no weirdness. Regular problems I can handle, the weird ones stress me.

The bike, ready for battle.
Custom Tsunami frame with a custom Steelman Bikes stem.

I brought T-shirts to the race. I bought too many, I think, since we need to sell almost 200 shirts to break even. The girls at registration did their best but I think I'll have a separate post on the t-shirts this week.

Anyway I wanted to take a picture of the bike with the t-shirt and there it is.

Some trackstand battles between the Series leader and his teammate.

I wasn't the only one feeling a bit better in the warm sun. The Cat 3-4 Series Leader was horsing around a bit, doing a track stand battle in the waiting area by Turn One. I left before someone dabbed so I don't know who won. It showed the team's spirit and camaraderie though, and helped demonstrate their tightly knit team. They've been super impressive each week they've raced and they definitely deserve the overall lead.

Rolling to the start.

Today we got a moto ref "on a trial basis" if you will. They have to do some races for practice so this was this moto's practice. It was so good that I think the federation should do a free moto for a field or two for all promoters, to give them an idea of what a moto can do for them.

Junior wants a hug before I race.

Before I got to the line I looked for the Missus and Junior. I'd spent a bit of time with them before (maybe that's why I was less stressed) and I knew that Junior was getting to the end of his tether. The Missus would leave with him before the end of my race so I wanted to say bye before the start. Junior wanted to hold me so I gave him a hug and said bye softly.

Following an early counter move.

The guy to the left will win the race, I think the guy up the road gets second, and the guy in blue, near the yellow line, third. If I could have looked even 30 seconds into the future I'd have killed myself to stay on the wheels.

Normally I sit in and such but today I felt a bit of energy in my legs. I got to the front and decided to fly the colors a bit.

I ended up pulling for a short bit.

When I say "a short bit" I really mean a short bit. I pulled a little, pulled off, but no one wanted to pull through. So I pulled sort of slowly until someone finally decided to go around, aka sort of attack. That brought a bunch of riders around me and I could get back in.

I'm still standing.

I had the legs to stay near the front for a lap or two more and then I did my customary slide to the tail of the field.

The Series Leader noticed me and commented that it was nice to see me out here. He's the nicest guy, a tribute to his team, a great spokesman for the sport of cycling, but he's so strong he didn't realize that I've been out here racing "against" him, just I've never actually ridden next to him because I'm always way back.

I grinned to myself after that comment because that's about when I went backward.

Waving to Junior.

I wanted to wave to Junior while on the bike. It's hard to pick out a particular rider in a field and I wanted to help him out. On one of the slower laps I took the chance and waved.

He was looking at me with total concentration, furrowed brow. I could tell his brain was working in overdrive, trying to figure out what was going on. He doesn't filter things like we do so he'll pick out a logo on a wall of product. His non-filtering works against him when he's trying to pick out dad in a field of cyclists - I think he has to look at every rider, at least every rider that has red on him.

Random lap, moto ref to the left.

The moto ref tooted the moto's horn a couple times. Regardless the racers were much more careful about the yellow line. I really liked it, having the moto ref looking after us.

Random lap, close.

I chose this picture because the rider close to me was moving ever so slowly to the right. I wasn't sure if it was intentional but I realized it was when he got really close. This was the closest I got to someone in the whole race. A non-incident.

During the race four guys eventually went clear. One guy blew and got dropped - the other three lapped the field. In the field many of us had no idea until the spectators started yelling, "They're right behind you!" The dropped guy time trialed ahead of us, trying to get his 4th place.

A lap later two Sixcycle guys went to the front, towing another NY rider with them, the third break racer. We'd gotten lapped.

With all the Sixcycle guys streaming by, with other guys jumping on their wheel, I had no idea how many lapped us. Maybe 4, maybe 6? I assumed it was 6 and that all the points were gone. This settled me mentally as I could focus on doing a sprint with no pressure.

2 to go.

Two weeks ago I had a good sprint, partially because I started in good position. I decided that I'd try to replicate that effort. Joel, my teammate to the front right of me, was looking to move me up so I stuck on his wheel.

I moved to the left only to toss my bottle, which I hadn't touched all race. I've started without a bottle only to want a sip of water, but I'm going to toss my bottle earlier if I don't drink from it early on.

Bell lap.

We hadn't gained much position and Joel had spent a bit of time (and energy) sitting in the wind. When things shifted around I had to get to the right to shelter from the front-left headwind on the critical backstretch. Joel, stuck on the left side, ended up stranded.

Backstretch, last lap.
About 550 meters to go, maybe 600.

I've moved more to the right to get shelter. I believe Joel's wheel is just on the yellow line in that shot. I saw the opening to the right but thought someone would come blasting up the side so I decided not to take it.

Still open to the right so I go.
About 400 meters to go.

Of course, 100 meters later, the hole was still there. Maybe I was at the back of the field, I don't know, but I went right and quickly scooted up to a Jordan racer in a white kit, black shorts.

Now shifting to the left a bit.
About 300 meters to go.

I moved to the left a touch, expecting a squeeze to the right, but no squeeze so now I had a lot of room. Again there was a gap to the right but I was hesitant to fill it, holding position instead. This is a tad under 300 meters to go.

The right opens up. The Jordan guy is now to my left.
About 250 meters to go.

The Jordan guy moved left while I still eyed the right side. I wasn't sure what would happen but the left side looked like they were going. I didn't want to risk getting boxed in on the right so I stayed middle.

The Jordan guy moves left, I do too.
Just over 200 meters to go.

When the Jordan guy moved left I did also. The Rockstar Games guy to the left was my outside lane wall - I couldn't move left through him so he defined the left border, the Jordan was a variable, the right curb was my right wall. The middle was good so that's where I went, following the Jordan guy.

The right side jams up.
About 200 meters.

Then the right side jammed up. I don't know if someone blew or what but suddenly the guys came backward. I shifted left to avoid the guy coming back at me, then shifted left a bit more as he tried to get around those in front of him.

Sprint starts to open.
100 meters? 125 meters?

I finally got some space and start to go. Of course It was still a bit crowded, with riders going forward and others coming back.

Sprint jams up.
15-20 meters.

Here a big Sixcycle guy is going backward, one of the two Sixcycle guys that lapped the field, and he's winning the race. His teammate, on the same lap as me, is on his last legs and slowing hard. I'm boxed in and have to wait for the lane to open up. I end up going to the right the Sixcycle guy on the same lap as me and to the left of the guy with the red swoosh on his shorts.

Yeah, there's no hole there but it opens up.

At the line.

Sixcycle to my left, Red Swoosh to my right. I sort of nosed the bike forward but I had very little momentum since I never really sprinted. It was one of those habitual things, a little poke forward with the bars, nothing dramatic.

Relative shot.

I'm glad I nosed the bike forward because I just barely nosed out the Jordan guy at the line. It was only for 9th place, so 5th in the field, but still, ever bit helps. Another 10 meters and I would have gained a few more feet.

In the sprint I went at 700 watts peak (as the right got blocked), eased, went at 900 watts peak (as I got some real estate), eased, then 950 watts (still in the real estate), eased really hard dropping to 0 watts and 5 mph, then did 700w peak and trailed off to the line (snaking between the two riders and then throwing the bike. We never got going, maxing out at about 33 mph, crossing the line at about 23 mph.

I did a cool down lap, very unusual for me, mainly because I was blocked from going to the left to get back to the trailer. Then I  stopped, chatted a bit with the guy that got 4th - he finished just in front of the field - and then headed over to the trailer. My race was done, now it was time to get to work.

One more race here and then it's on to the rest of the season. Yay.

Equipment - Radical Steelman Stem On Bike

A few people have asked me what my stem looks like on the bike. I posted a pretty distorted picture that really makes the stem look ridiculous so I wanted to post something a little bit better.

The distorted picture, a still off the helmet cam; the stem was unpainted at that point.

When you look at that picture it looks like the drops end up below the 60mm fairing of the front wheel. The saddle looks like it's a good foot up in the air (I guess my National Lampoon style taillights don't help either). Although I have some saddle-bar drop the picture makes it look just a little bit ridiculous.

Therefore I lugged the camera down to the basement take a more reasonable picture.

The now-painted stem on the bike, in the trainer room.

I took the picture kneeling, hiding myself from the camera by placing myself behind the head tube of the bike (meaning so I don't appear in the mirror, or the flash in the mirror doesn't drown out the bike). The drops are shown a little more accurately in terms of relative drop.

Of course my kneeling position makes the saddle look like it's pointing up but trust me, it's not. It's level with a little dip in the middle. However the saddle doesn't look like it's towering over the bike like it does in the first picture.

The drops end up in the same spot as they were before, about next to the tire. Due to the compact bars, with their 3 cm shorter reach and 3 cm less drop (meaning it's 3 cm higher), I commissioned Steelman Bikes to make me a stem that would situate the drops properly.

They did and it does.

Yesterday I went on an Expo ride and the unstoppable Heavy D had his helmet cam on. I grabbed a couple stills from there to illustrate that my position on the bike isn't nutty as the stem makes it look.

In the paceline. I'm on the right, in case you didn't realize.
(still from a clip by Heavy D)

I admit I do have a flatter back than many riders out there, but it's because my back hurts if I ride in a more upright position. Another Expo rider, chatting with me on the roll out, theorized that the longer, lower position would reduce the load on my back by transferring it a bit to my hands. That makes sense. My back is definitely my weak point and it can be almost crippling at times. Riding on the drops is almost like therapy for me, easing the discomfort and making things much more manageable as far as my back goes.

Of course it doesn't hurt that it's aerodynamic or anything, but if my back forced me to sit upright that's what I'd be doing instead.

Making an effort following a hard working Jeff.
(still from a clip by Heavy D)

My position isn't radical at all. My arms are a bit bent but the low drops isn't meant to give me straight arms or bent arms or anything like that. It's meant to give me a good position when I'm out of the saddle and my only contact points are the pedals and the drops. I need the drops to be low enough that I can pull up on them and so that the front wheel gets a bit of weight on it. With higher bars (by 3 cm) the front end got really skittery, making the bike hard to control in sprints. My short legs determine the bar height, not any need for mucho drop.

Unfortunately I was behind Heavy D when I made my rare jump efforts on the group ride so there's no shots of me actually going hard out of the saddle from that ride.

You may notice that I have a saddle bag on my bike. I normally carry stuff in my pockets but with a limited amount of pocket real estate on my jacket (one huge pocket, one key pocket), plus the fact that the stuff was moving around too much on me in Florida, pushed me to use my saddle bag again. It's nice - no worrying about it, not as much weight bouncing around in my pocket, and easy access (I tightened a bottle screw just before we rolled out).

So that's the bike. I need to get a second stem for my other bike, so that I have two bikes with the same set up. There are other maintenance things I need to do, mainly gluing tires, but for this year that's the only significant change I'll make as far as the bikes go.

Equipment - Steelman Stem, Part Deux

So I have a custom stem from Steelman Bikes. I put up a shot of it on the bike but nothing really detailed. I didn't have time to work on posts and such but now I do so you get to see the stem and all that I've done with it so far.

First the stem arrival and stuff is detailed in this post. Other than the one distorted picture of the stem on the bike you really can't tell much about the stem so now I'll try and explain how the thing looks and how it positions the bar relative to the previous set up.

Distorted picture of the bike.

I went through a thinking/exploration process in the fall after deciding to commit to a custom stem. I could either limit my bar selection to "deep drop" bars (I couldn't find one I liked) or I could use a compact type bar (which I like) and get a stem that would allow me to choose virtually any compact type bar for my bike. The custom stem made more sense so I thought it through and ordered it.

I have to admit the numbers would make even my back ache - a 14.5 cm stem with a negative 32 degree rise. However, once you see where the drops are before and after, you'll see that there is virtually no change in the drop position.

The FSA Energy bars, 15 cm drop, with a Deda Pista stem (-20 degrees, 14 cm).

These bars felt high and the drop shape made them effectively higher than the 15 cm "drop". I grasp the bars where they're a bit curved so I don't use the flatter part, which is where they measure the drop. Therefore the drop to where I hold the bars ends up in the 13 or 14 cm range, not 15 cm.

The FSA Wing bars, 12 cm drop, with the Steelman Bikes stem (-32 degrees, 14.5 cm)
This was during my first trial ride so I hadn't moved the levers/cables over yet.
Note the cut down bars - I cut them down when I first got them an eon ago.

The drops angle isn't quite right but the bars are next to my tire, which is approximately where I need them based on my BB height. Remember, the whole point of the exercise was to promote stability and power in the sprint, which for me is out of the saddle. In such a sprint I only have two main contact points - the bars and the pedals. The pedal position is determined by the bottom bracket location and the crank length - those are not very negotiable. Therefore I need to bring the drops to the right place relative to the bottom bracket.

A slightly zoomed out view of the stem. The bar is next to the tire, give or take.
I took this picture after moving the levers over. By now I'd committed to the stem.

As some sprint experiments showed me the stem works great. However, in its raw steel state even a long week in Florida led to some noticeable surface rust. I decided that before I got back on the bike at home I'd need to paint the stem. I had some zinc-permeated primer (zinc is what they dip car bodies in so they don't rust like they used to in, say, the 70s) and some chassis paint (specifically designed to be chip resistant; I got it for the Expedition) so that's what I used.

In the "paint booth".
The front cap was already black so I left it alone.
Blue tape to protect clamping surfaces and threads.

I will not criticize a paint job again.
The front cap came that color, a matte black.
The next stem, for the black bike, I'll have Steelman powder coat it or whatever for me.

I remember when I had the Z that some people commented on the poor paint. Okay, I had perfectionist body shop guys who work on exotic cars all day criticize the paint, one even doing so unknowingly in front of me. That led to a whispered, "Dude, the guy over there owns this car," and a muttered, "Oh."

I never really noticed whatever was wrong with the Z's paint so it didn't bother me. However even I can tell that I did a crappy job on my stem, just like I did a crappy job on a black BMX bike when I was in high school.

(The BMX bike started out as a 20" wheels TT bike project and I bought the bike because it had tear drop shaped tubes but that's a whole different story.)

I will never criticize a paint job again, at least not until I know how to do it right.

I ended up with what I'll call a "20/20" paint job. It looks fine from 20 feet away or at 20 mph, at least to my uneducated eyes. Maybe those exotic car guys would rate it a 50/50 job. Still, for me, I wanted to keep the rust away from the stem and so far it hasn't rusted so it's good enough for me.

On the bike, with the safety spacers on top.
Note the not-so-shiny part in the middle - that's the 20/20 bit.

Now the bike sits on the trainer, destined to be there for the next couple months. I need to adjust some cable lengths - I already shortened the rear brake cable but I need to shorten it more. The front brake is a bit of a puzzle since the cable ends up snaking up to get to the barrel adjuster on the brake. In Florida I tried to run the cable over the top of the bar but it looked horrible and it didn't reach and I didn't have any extra cables or Nokon housings and liners. Here at home I have both so I might spend some time fiddling with it.

All in all though the position in the drops feels great. I feel hunkered down and stable and that's all that I wanted from the stem.

I don't know if I'll get it ride it outside. Taking pictures of my bike right now is a bit tough so I'm afraid that's what you get for now. All willing it'll be out racing and sprinting in March and I'll be able to get some better shots then.
