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.

Equipment - Bar Drop Delta

Yesterday I alluded to this idea I wanted to explore further, related to the two different levels of drop on two handlebars on my red bike.

As a reminder I'll show the two bars. First is the Wing bar, the shallow drop one:

FSA Wing bar, shallow drop.
Note the drops are above the tire.

FSA Energy bar, deeper drop.
Note that the drops are about even with the tire.

For the longest time, after seeing pictures of Michele Bartoli at his peak, I wanted to have a shallow drop bar that allowed me to have a very low position even when on the hoods or tops. My rationale went as follows - since glute recruitment correlated directly with how far over I was leaned over, I wanted to lean over more all the time. This way I'd be using my glutes more - I'd be more powerful.

Plus it's more aero so if I was alternating standing and sitting on a fast uphill I could go faster if I was lower.

Bartoli in action with his super low bars.
I understand this was "that era" but the position is what's important here.

I know that I can simply lean over more while using a shallow drop bar, but that stresses my back. It's already messed up so I want to try and keep pressure off of it, and that means having a certain amount of extension with my arms, allowing me to support my upper body without much effort.

When the compact bars first came out I didn't really think of them as a solution to any problem I might have because, frankly, I like more reach and more drop, stuff the compact bars reduce. Then I realized that, hey, this might be the way to get the drops and hoods closer in height, allowing me to realize that Bartoli type hood/top position.

If I used a longer, lower stem I'd be able to put my hand positions in a tighter cluster, less delta in drop from the tops to the drops. This meant I would be closer to my "drops" position the whole time I was on the bike. This in turn would mean I'd have more power due to the fact that my body could recruit those powerful glutes and other muscles all the time, not just when I was in the drops

So I went out and bought an FSA Wing bar, a compact bar with a flattened top bit. More aero, right? I couldn't go wrong.

I also had to buy a longer, lower stem, I returned to shorter 170mm cranks to push my saddle up 5 mm, and I even contemplated changing pedals which had more "stack height". I needed to get higher on the saddle so that my bars would be the appropriate drop down.

The problem was that even with all that the bars were simply too high. The tops were fine but the drops were 2 cm higher up. I felt better on the tops, the hoods were basically the same, but the drops weren't great. They felt worst when I was sprinting out of the saddle. Unfortunately that's the most important thing for me.

The drops had to drop.

This led me to buying some FSA Energy bars. They have the same reach as the Wings but they have more drop, 2 cm worth. This would put me right back where I wanted to be, back to the amount of drop my crit bars had (which, in the old days, wasn't considered much). The only thing was that I had gotten to like the bend of the FSA Wing drops and the Energy drops looked different.

Therefore I avoided making the change, trying to make the Wing bars work.

Finally, last week, I gave up. I tried the Energy bars with their deeper drop. I immediately felt the difference. Although the Wing bars had about the right reach the Energy bars felt just right, like slipping on a pair of well fit jeans.

After two rides on the trainer I decided that the levers were positioned okay on the Energy bars. This meant wrapping the bars and heading out on the road.

To my amazement I trucked along on the deeper drop bars. They felt good, much better than the shallow drop Wing bars. I wasn't sure exactly what it was but obviously it had to do with the extra drop.

When I got back home the Missus asked me what route I rode because I got back too early for my regular loop. I told her I'd done just that, the regular loop. After checking Strava I saw that I set a PR for one section and top three times (for myself) in every other public segment. I'd done my loop faster than I'd ridden it since early 2012 when I started using Strava religiously to track my rides.

The next day I felt unfamiliarly sore, aches in my shoulders, arms, even the backs of my legs. The lower drop position had me recruiting neglected muscles.

I realized that the deeper drops allowed me to recruit more muscles. That implied that I'd be using my "regular" hoods/tops muscles a little less. Spreading the power stresses across more of my body would allow me to use more muscles, allowing me to use different muscle groups as I fatigue.

I have yet to race with the Energy bars but with four races coming up in the next month or so I'll have plenty of chances to test them out. It'll be interesting to see how it goes.

Equipment - FSA Energy Handlebars

Over the last month or two I've been thinking about trying to fix my bar position. I mean, okay, I've been thinking about it since the winter, but I finally got another bar that might work - the FSA Energy handlebar. I was running an FSA Wing, a "compact" bar. It has 12 cm drop and 8 cm reach, instead of the 15 cm drop and 11 cm reach of the crit bend bars.

To try and make up for part of this I got a 2 cm longer stem (14 cm long) which moved the drops out 2 cm and therefore reclaimed 2 of the 3 cm lost. I'd be running 1 cm shorter reach.

I got the stem in a Deda Pista (track). Unfortunately instead of the normal 65 degree angle the Deda came with just a 70 degree angle, a whopping 3 degrees downward angle from horizontal, not the 8 degrees I wanted.

Ultimately the stem got me another half centimeter of drop, netting me a 1.5 cm raise, versus the 2 cm raise before. I knew it affected my sprint negatively but I decided that it would be acceptable. After all, 2013 was the year of no goals, just to ride and race as possible. Sprinting on the drops felt awkward, kind of like doing curls but just the top 25% of the motion. I want to get into the meaty part of the curl, the middle 90 degrees, not the top 45 degrees. The shallow drop bars kept me from really being able to push/pull the bars.

The big benefit to me was that the tops of the bars were 2 cm further out. I really liked that for the JRA type training I do out on the road - tops or drops for me.

Since the higher drops grated on my nerves every time I rode I decided to look for a deeper drop 8 cm reach bar, so a deep drop compact if you will. I saw the FSA Energy fit the bill, so when I could I bought one.

Then I let it sit around for a month or two. Or three even.

The other day, reluctantly getting on the bike for a hot trainer session, I decided that, okay, I'll try the doggone bars. I'd gotten a 73 degree 14 cm 3T stem as well so I bolted the two together, making it a Road/Energy combo, and stuck it in place of the Pista/Compact bar set up. I didn't bother transferring anything over to the new bars - if it didn't seem right I'd just put the complete Pista/Compact cockpit back on the bike.

Road/Energy stem/bar combo, bare.
Note the regular Pista/Compact assembly dangling below it.

Another view which clearly shows how I simply put a different bar/stem on the bike.

I rode the trainer like this. Shifting was awkward at best. Trying to check ride time on the SRM involved moving the dangling bar a bit so I could see the SRM.

A sideways view (left is down), showing the Pista label on the original stem.

I did the trainer ride with the Road/Energy set up, no cables, no tape, and even though the skinny unwrapped bar felt incomplete the overall setup felt better. Shifting the other sets of bars inconvenienced me, of course, but, more significantly, I noticed the 2 cm drop immediately. It felt better, it let me drop down lower while on the drops, and it felt like it ought to work. I even rode with gloves because the bar bars slipped too much. The drops themselves felt weird so after a not-too-intense ride, tired in a sleepy way, I decided to deal with it later.

The next day, when I looked at the bike with a clear mind, I realized that I never properly tightened the handlebar clamp bolts so the bars tilted up when I pedaled while holding the drops. The ends of the bars were pointing comically at the rear hub.

I had ridden a clown bike.

This is why the bars felt so weird on the drops, and in the dimly lit room (it was late at night), a hazy brain, I just didn't see it. I tilted the bars to a more reasonable angle, pointing to just above the rear brake, and sat on the bike. It felt okay so I spent some time moving the cable housing and levers over. I even moved the SRM mount over.

With no tape I did another trainer ride, again with gloves. Unfortunately I bonked on this one so I ended it quickly. Even in the short 35 minutes I realized that the right lever sat just a bit higher than the left and that otherwise the bars were great.

The next day, with the Missus's encouragement, I adjusted that lever just a touch lower in preparation for wrapping the bars. The cable housing seemed just a touch too short, just enough to make me feel slightly uncomfortable. I thought about lengthening the housing, something that you can do with the Nokons, but then I realized that maybe the Pista stem, with its 3 degree downward slope, would help. I quickly switched out the 73 degree 3T road stem for the 70 degree Deda Pista and lo and behold the housing looked okay. Amazing what a few millimeters of drop can do.

A final check of the lever level and the bar angle and I wrapped the bars. I bought some Fizik tape for its grip in the wet, to replace the set on the Compact bars. I'm not keen on how it doesn't really stretch but that's okay. I think I need to get cheaper tape in quantity so I can keep fresh tape on the bars.

I headed out for a proper road ride, complete with out of saddle efforts and such. The deeper drops felt great, familiar, like getting back into the groove again. I tried to remember the different positions, the different efforts, spinning, sliding a bit forward on the saddle, sliding a bit back.

The forward position worked well, tilting the pelvis forward, flattening my back, allowing me to spin. I could hold the bars with little effort, no stress on my arms, no stress on my back, unlike trying to hold a low position with the shallower Compact bars.

Although I focused on the position, on making sure the bars were straight, the angle was good, and the levers were level, I got back home a bit quicker than normal. The Missus queried me on the loop since I was back a bit quicker than expected - I did the loop in a bit under 50 minutes (about 18 mph). That's better than an hour or so, not as good as the 43 or 44 minute lap I did one time (over 20 mph).

The drops felt better, the tops felt the same, and the hoods, for some reason, felt better when I was standing. With a slew of races coming up I'll have some time to see how the bars work for me. I have races scheduled for Tuesday Aug 6, Saturday Aug 10, Sunday Aug 18, Friday Aug 23, and then finally Sunday Sept 22.

I have more thoughts about the deep drop bar (or, really, the "normal drop" bar) but I'll post on that later. For now some pictures on the bike with the Energy handlebars and the Pista stem.

The bike pretty much as I rode it for the first time with the new bars.

Notice there's no bottle? No frame pump? Yeah, I forgot that stuff. Oops. I got on the bike after the first attempt at pulling Junior along in a trailer. That wasn't a great success. It took a while to figure things out though plus we waited through two short rain showers. When we finally got back from our 1 mile outing it was getting late. I basically jumped on the bike and left, sans bottle and pump. I did have my pockets full with my tools and stuff but yeah, brain scattered results there.

Slightly better view of angle of bars.

You can see the the drops are about level with the tire. This is where I'm used to having my drops, there or slightly below.

For comparison here's the Wing bar from an earlier post.
Note how the drops are above the tire? Not good for me.

Normally I cut the last couple inches of the bar off but I didn't have the wherewithall to do that so I just left it as it. Seems awfully long - on a normal top tube length bike I'd worry about hitting it with my knee. I'll cut it down the next time I wrap the bars, with the end of the bar a vertical line down from the back of the tops of the bars.

Slightly different angle of the Energy-based cockpit.

You can see the slight downward angle based on the garage door lines. It's a very slight angle. I'd prefer to have a 3 cm shorter head tube and an 80 degree stem but that's not possible. A downward angle stem is the only real option.

From above. The SRM is missing - I had that on when I rode.

Now to see how the bike works at the next race, either tomorrow at the Rent or Saturday at Rocky Hill.

Equipment - Tsunami 1.1 or "The Now-Red Orange Frame"

For over a year I've been wanting to get this frame back online. It started out as my original Tsunami frame, with the now-standard-for-me geometry - 40 cm seat tube, 56.5 cm effective top tube, 75.5 degree seat tube angle, 73 degree head tube angle, and designed to be used with a 43 mm rake fork.

The original bike, shortly after I built it up in SoCal.

This makes for a long bike to fit my long torso. It's not very tall though, to fit my not-very-tall legs.

The original Tsunami (version 1.0) had industry standard 40.5 cm chainstays and that's where it faltered. Even coasting in fast corners the rear tire would chatter or slide across the pavement. The unusually long front end meant I had too much weight up front, leaving the rear wheel to fend for itself.

This, along with my short-lived upgrade to Cat 2, instigated the second Tsunami, the black one. Geometry-wise I wanted the same bike but with "as short as possible" chainstays. Those ended up measuring 39 cm in length.

The black Tsunami (version 2.0 if you will) also had some aero features. I wanted the narrower tubes with the thought of racing with a CamelBak. This would eliminate the very bulky bottles from the bike, allowing me to take advantage of the aero tubing.

My CamelBak idea faltered because I didn't like the way it worked (can't toss an empty CamelBak, can't empty it all the way, pain to refill, warm in warm weather, harder to breathe, etc). I resorted to using the bottle bosses, literally an afterthought in the build process.

"Might as well put them on although I don't plan on using them."

The black frame worked well although the nut that held the seat down (aka "the rider" aka me) wasn't as good.

I started thinking of combing my favorite elements from both bikes into what would be a Tsunami 3.0 - internal cabling (easier to clean), short chain stay, regular tubing.

On the off chance that Joseph (aka Tsunami Bikes) could alter my orange frame I contacted him. He told me no problem, he could put new chainstays, seatstays, and a brake bridge on for me. I didn't realize it's just trimming one tube; he'd have to rebuild the whole "stays" area.

I decided it was worth sacrificing the internal cabling to save 6/7 of the money a new frame would cost me.

Joseph sent the frame back unpainted (per our agreement) and I had a local car nut paint my frame the same color he was painting his Mini. It happened to come out red so fine, red it was.

I also invested in some frame prep tools, specifically 1 1/8" head tube facer/reamers and a BB30 reamer, ordering them through Expo Wheelmen sponsor Manchester Cycle. These cutting tools, combined with Manchester Cycle's cutting tool handles, would give me a perfectly finished frame. The frames arrived unprepped and the headsets were always a bit tight and the bottom bracket was also. Bob, the owner of the shop, did the work himself, and the red frame (Tsunami 1.1) came back to me ready for assembly. This would save me a few watts turning the cranks - it's bad enough that I can see wattage numbers pop up on the SRM when I'm soft pedaling (i.e. not keeping up with the wheels)

That process dragged on for months while I realized I was missing this piece or that piece. Minor things roadblocked the build, like a front derailleur hanger, or cable housing (I ran out of Nokons), or trying to figure out what stem would work with the FSA Compact bars I wanted to use.

Finally, before the April 7 2013 Criterium de Bethel, my bike was ready to ride. I wrapped the bars at the prior March 24 Bethel CDR Gold Race, rode it on the trainer before April 7, and did my shake down ride during the April 7 Cat 5 clinic.

It seemed to work okay so I put the race wheels on it.

Tsunami 2.0 to the left, 1.1 to the right.

Note the different shaped bars. The Compact FSA bars on the red bike are 3 cm shorter in reach and 2 cm shorter in drop. To accommodate this discrepancy I have a 2 cm longer stem (so 1 cm shorter overall) with about a 0.5 cm drop (so the drops sit about 1.5 cm higher).

For the Cannondale SI cranks I have two sets of arms, 175mm and 170mm. The 170s came with my Cannondale (Team Replica blah blah blah bike). I bought a used SRM setup that had 175s. In the past 10 years I've had much better results with 175mm crank arms, I think due to my lower general power.

170mm and 175mm crankarms on the Cannondale.
Picture taken in SoCal just before I moved the parts to the orange Tsunami.
What's nice is that you can change the crank arm without changing the spider (that holds the chainrings).

However I chose to install the 170 mm crankarms on the red bike. The shorter arms give me an extra 0.5 cm in saddle height. The resulting net height difference is about 1 cm less drop to the drops. More significantly the drops are about 1.5 cm higher relative to the bottom bracket. When I'm sprinting out of the saddle that's the height that matters. We'll see how it goes. If it doesn't work out I'll revert to the old style crit bend bars and I may have to go buy a second set of 175mm crankarms.

A final change, but I'll expand on that more later. I'm using a lower end brake lever, one that doesn't allow multiple shifts into higher gears. It's one click at a time, no more dumping 2-3 gears when I jump. I'll explain this move in a different post.

I accidentally used my last name rather than the Sprinter Della Casa sticker.
I want my name to go on my hubs and helmets. SDC goes on the bike.

Note the smoothed out finish around the seat cluster. It's a combination of gentle filing and an expanding primer. The primer puffs up when applied and then hardens. The guy who painted his Mini showed me the roof - when he started it looked like someone dropped a bucket of golf balls on it from a couple floors up. When he was done with the expanding primer the roof was perfect. I bought into the expanding primer idea.

Deda 14 cm Pista stem.

"Pista" is misleading here. I wanted a 65 degree (-25 degree) 14 cm stem but I couldn't find one. I felt the reach (14 cm) was more important than the height (65 degree) because I was already compromising my reach by going 1 cm shorter. Going 2 cm shorter with a 13 cm stem would be really significant because I tried it already. I figured by using shorter cranks I'd have an extra 0.5 cm in saddle height. Therefore I sacrificed the drop to get the 14 cm stem. The Deda "Pista" stem is only 70 deg so about -20 deg. It barely drops 0.5 cm.

In order to have 100% clamp surface for the stem I left the steerer tube too long and used spacers on top of the stem. This way the whole height of the stem clamps the steerer tube, not all-but-the-top-5-mm.

Close up of tire clearance.

The chainstays are about 39.2 cm. I have to measure them again because I keep forgetting what they measure but they're just a touch longer than the black bike's 39 cm stays. There's plenty of fore/aft clearance. To the sides it's bit tighter.

The head tube area. Note how smooth it is compared to the first picture in this post.

It's a bit smoother than before, primarily due to the expanding primer. I put clear frame protector stickers on by the cable housing. I had to stretch the black Nokon housing by adding extra blue and silver segments. I'd have run out otherwise.

The headset is a super low stack Cook Bros headset. It's a bit of a pain to install but Manchester Cycle did it fine. I installed the orange bike's headset in my basement using unofficial tools. The black frame got its headset installed by a SoCal shop during that year's SoCal training camp. I use the same type of headset on both bikes, just the black one got a steel headset and the red one has a stainless one.

Not exact but you can see the drop/reach.
Wire sticking up is for the SRM, two wires carefully taped up into one.

The bars drop more with the old crit bars and they reach more.
SRM wire is hanging forward and down. I need to rewrap that, it's unraveling.

If you look at the two bars you'll see that even though the FSA Compacts on the red bike are longer on the drops (I wasn't as aggressive when I cut off the excess bar) they obscure more of the front brake. They don't drop down to the tire also.

The black bike, with my standard position, shows how the old crit bend bars drop down more and reach out further. Keep in mind that the black bike as a 12 cm stem, 73 degree (-17 degree). The red bike has a 14 cm stem, 70 degree (-20 degree). Due to the FSA Compact bar geometry I lose both reach and drop even after using a longer and lower stem.

You may have noticed a lot of barrel adjuster showing on the red bike. This is so I don't have to unclamp the brake cable when I switch between the "wide" clinchers and the wide tubulars. The clincher rims are only 23 mm wide but that's the "wide" size. Normal is 19-20 mm.

The tubulars, on the other hand, are close to 28 mm wide. I bottom out the barrel adjuster to clear the tubular rims. It's about 5 turns difference between the two.

I have normal 19 mm wide clincher wheels but they're far too narrow if I want to use the wide tubulars. They've been relegated to the basement.

I have new-to-me wheels but I'll cover those later. Right now they've become my default race wheelset.

I've only ridden the bike a few times now, once in a race, once for a few laps in a Cat 5 clinic, and three times on the road. The biggest thing I noticed is that the bike seems to move more freely. It's due to the reamed/faced bearing surfaces - the bike steers eagerly and the cranks turn easier, even if I'm soft pedaling down a hill. It feels a bit like riding rollers - the bike wants to skate around a bit. It's not a bad thing to have the bike feel more eager to go, that's for sure.

The other thing is that the top tube is a bit lower on this bike. It means I can't put a frame pump under the top tube - the space is too tight for the Park pump I have. It does fit on top of the top tube though and it's where I had it the last time I rode. I may rig up a front-skewer-to-bar thing or a rear-skewer-to-seatpost, depending on how easily I can set one up.

I have a few good scratches on the frame already. The bars turns hard into the downtube when I was building the bike - no tape, no bar plug, a coarse hacksawed bar end. The downtube has a good gouge/nick in it now. And yesterday, when I finished my ride, I sat on the frame pump and it scratched the front of the seat tube above the top tube.

Ah well.

It's now a race bike because I raced on it. And it's a training bike because I trained on it. Such things will happen.

Equipment - Making FSA Compact Bars Work

'Tis the (off-) season, as they say.

I've been a bit negligent in putting up posts this year, primarily because of a lack of time. My time crunch has led to less "things" to blog about, whether they be group rides, equipment stuff, or even life experiences. I've tried to keep Junior out of the posts for the main reason that he doesn't directly have much to do with bike racing.

I found it difficult over the summer to get in a training ride a week, often relying on just racing on Sunday and Tuesday (when the Missus and I would share Junior duties). At home, when the Missus suggested I go for a training ride, I usually spent the time sleeping instead.

Looking after Junior, apparently, is more tiring than training.

Nonetheless I've started thinking about the 2013 season. I have modest goals for it, nothing really major. Basically I just want to be competitive again. I'd like to drop to something close to my 2010 weight, knowing that the lower weight will automatically bump up my performance (regardless of training). I raced at about 158-160 lbs in 2010. In 2012 I was racing at 170-175 lbs. Although "just" 10 pounds it made quite a difference in acceleration and in climbing. In a race where I finished strongly in 2010 I got shelled almost immediately in 2012.

Not good.

I also need to straighten out my equipment situation.

I threw around the idea of getting another frame built, to accommodate the FSA Compact bars I like so much. Unfortunately the lack of drop (short by 2 cm) and reach (short by 3 cm) meant that I'd either need a custom-custom frame (59.5 top tube and a 7.5 cm head tube) or a bizarre custom stem (65 degree 15 cm stem).

On further thought I realized that even if I got the longer frame I'd be compromising my weight distribution. I'd be putting my front wheel forward an additional three centimeters forward, reducing weight on the front tire and therefore reducing traction up front. I already slide forward on the saddle in turns, trying to push the front wheel into the ground, and starting three centimeters further back from the front wheel doesn't make sense to me.

Therefore I decided that I'd work with the frame I have now, the now-red Tsunami, and try and fit it so I can use the FSA Compact bars. I came up with the following plan.

First I'd use a 14 cm stem. Going from the 12 cm I'd get an additional 2 cm of reach, gaining back all but 1 cm of reach I lose when going with the FSA Compact bars.

Although a little known fact, because I never told anyone, I went to a 1 cm longer stem between 2010 and 2011. I'd be returning to my 2010 position in terms of reach.

To deal with the 2 cm shorter drop I'd do a couple things. I can't drop the stem because it's already dropped down to the headset, the headset is a super low stack height one (it's really short), and the head tube is as short as possible. Therefore I can do two things - increase saddle height or use a lower stem. Doing both would probably get my 2 cm back.

I managed to source a 14 cm track stem that points down a bit. I think I'll get about 5mm of drop, maybe 1 cm if I'm lucky.

The track stem


It's 14 cm long. Only 70 deg, not a 65 like a true track stem.

I'm also going to be running 170 mm cranks. I have two SRM spiders and two sets of crank arms, 170s and 175s. I'll leave the 175s on the black bike and put the 170s on the red bike. Being 5 mm shorter I'll have to raise the saddle 5 mm. This gains back 5 mm of drop.

With these two changes to the bike I should get back at least 1 cm of drop, maybe 1.5 cm of drop. I figure I should be okay with that.

If things work out then I may have to find a couple more 14 cm track stems and an extra FSA Compact bar or two.

Then I'll be able to use the sweet bars that I tried early in 2012 but rejected because they were too close and too high.

There's more to do than just bars so I'll go over that in the near future.

Equipment - Tsunami 1.1

Tsunami Bike 1.1
(Some assembly required)

It's a start I guess but I haven't really gotten very far in the year or so that I've been "working" on this project. In this picture you can see some hints at what will be on the bike at the end. The frame is the main thing, of course, and it has one sticker on it so far, the bottom bracket (BB30) has been reamed, and the head tube reamed, faced, and a headset pressed into it, all done by Manchester Cycle.

The main modification has been to shorten the frame's chainstays as much as possible, this to pull the rear wheel in. Due to the long front center the rear wheel gets really light, losing traction in any hard turn. The short stays really help counter that (as proven on the black bike, aka Tsunami 2.0), and so I had the first Tsunami modified in a similar fashion.

1. ENVE 2.0 fork, with the same Crank Bros headset as before, a very low stack height (22.x mm) stainless steel number.
2. Campy cassette. I actually have four in this picture, one in the box, three in the plastic bag just above the silver bars.
3. Campy brakes, in the Campy boxes that don't have pictures on them. I may just put the Ultegra brakes on (they were on the carbon Giant) but all Campy sounds better. There's a small surprise on the brakes and I'll reveal all when appropriate.
4. Campy new style 10s Ergo levers. I want to give them a try, and my backup shifters are starting to fade hard.
5. Cinelli 13 cm track stem, in case I want to give the FSA Compact bars (the black bars above the plastic bag) a shot. The Compacts have 2 cm less drop, 3 cm less reach, so I'd need a 15 cm stem that drops 2 cm to replicate the same drop position.
6. Fizik Tares saddle. I saw these at the time trial, they looked good, and based on that I bought one as an experiment. Failing that I'll stick with the Titanio saddle that is on the Thomson post.
7. Fizik tape, just because it was there at Manchester Cycle.

The box has a lot of tools in it too, the Park BB30 tool, a Park carbon-specific cutting blade for a hacksaw, grease gun screwed onto a Pedros grease tube, anti-seize (obscured), carbon assembly paste (obscured)

In the parts boxes somewhere are new brake and derailleur cables (other than the cable kit that came with the shifters). I'll use Nokons for housing and am debating if I should buy some fresh segments for the exposed sections. I'll definitely use the played out segments under the bar tape.

I have a BB30 axle for the Cannondale SI SRM cranks (it's a different length from the standard axle, of which I have one too), and a second SRM spider for said cranks. This way I'll have two bikes set up with the SRM. I have a second SRM PCV head, harness, and mount, so I won't need to set the slope (basically a setting for each spider) when I change bikes.

The derailleurs are coming off the carbon Giant.

And that's really it, now that I think of it. I want to buy some black bottle cages because the blue ones from the Orange Period will clash with the red.

Now, reviewing this post, I'm wondering why it took me so long to even think about starting the assembly.
