Equipment - Exustar Pedals

Note: I bought these pedals myself and paid more than the current MSRP for them.

Back in the late 90s I was trying to wean myself off of the Aerolite pedals. They were super light - about 70 grams per PAIR with the cleats - but I was running out of cleats and my drilled out shoes were pretty played out. Aerolites were about the most user-unfriendly pedals ever, so there was that. Finally I was pretty poor and couldn't afford to buy the in-vogue Look or Time pedals.

The Shimano SPD-Rs were very high quality pedals but they had one big drawback - the cleat often moved before the pedal would let go of said cleat. This meant that there were times where I had to ask for help unclipping from my own pedals. I usually hit the outside of my heel with a fist to unclip; just twisting my leg usually moved the cleat rather than unclipping me. I had the tension set to almost minimum, just enough to hold my feet in. Obviously this wasn't ideal.

However, at that time, the SPD-Rs were attractive to me for a different reason - price. They were super inexpensive because of their poor unclipping performance. Wholesalers sold them for less than half price. In addition I had a number of friends who tried and hated them and they gave me their pedals. I quickly built up a collection of 3 sets of Dura Ace axle pedals. Because all the wear items are steel, both on the pedal and the shoe, these pedals will last forever.

(This crank is a triple crankset, used temporarily while I tried out track racing)

About 10 years ago I moved from the SPD-Rs to the Look Keo Carbon pedals. The incident that really pushed me was when I had to have two people help me unclip on a group ride. I literally couldn't unclip on my own, and I started worrying if I could unclip when I rode. It was really stressful and not good at all.

When I tried the Look Keo Carbon I was happily surprised. I could release from the Keos easily without risking twisting the cleat on the shoe. I did have to max out the tension on the Keo Carbon to keep my shoes clipped in, but I didn't think that was a big deal.

The Keo Carbons.

A few years later, as my pedals started to show signs of wear, I went and bought two sets of the Look Keo 2 Max pedals. These were supposed to be the new and improved Keo Carbon. The Keo 2 Max had a metal plate on the top so the cleat wouldn't wear the pedal and ease unclipping.

(I think it's called the Keo 2 Max, it's the metal plate topped version of the Keo Carbon but with a regular plastic body. I'll call them the Keo 2 Max going forward.)

I didn't bother getting a better picture of the pedals.

When I went to the Keo 2 Max I experienced a spate of unclipping incidents. I unclipped while seated, while standing, all in higher power situations. I thought it was a worn cleat (at some point my cleats were worn) or inadequate tension (I maxed out the tensions).

I reinstalled the Keo Carbons rather quickly and the unclipping incidents stopped immediately. I put the Keo 2 Max pedals on my mountain bike (which I ride on the road). Using the pedals back to back I realized that the Keo 2 Max was so easy to unclip that I was unclipping inadvertently, even on the mountain bike. The Keo Carbons held my shoes much better.

With the Keo Carbons long discontinued I didn't know what to do. The pedals were pretty worn but I continued using them. If I had to I could always go back to the SPD-Rs, which I had on my track bike. I could also go to the Shimano pedal, which others have recommended. However I wanted to stay with the Keo cleat, only because I had so many cleats. And it'd be easier to experiment if I didn't have to change the cleats, just the pedals.

I asked someone in the know for advice. He suggested trying the Exustar pedals. Look users reported the Exustar pedals a bit harder to unclip, but for me that would be ideal. I bought a couple pairs of the pedals.

And promptly misplaced them.

Fast forward a year or two to a few months ago. I was organizing some innertubes and found the Exustar pedals buried in the dozen or two innertubes. I pretty much immediately put the nicer Exustar pedals onto the bike. I was pleasantly surprised to see that I only needed about half tension to replicate the release tension of the maxed out Keo Carbons.

White shows dirtiness quickly - these pedals are virtually brand new.

This is the Exustar E-PR2 pedal in white. They're inexpensive - MSRP $91 - and are basically a Keo Carbon type pedal. No metal plate on the pedal body, a wider platform than the PR1 (which is like the Keo Classic). Their PR3 pedals have the metal plate. The PR1 and PR3 are available with a titanium axle. For me, after breaking a titanium BB axle, I won't do titanium axles anymore, plus the weight savings are negligible in the scheme of things.

If the pedals look like the Garmin Vector powermeter pedals, you're right. Exustar makes the pedal body for Garmin, and it's basically this body except with the metal plate, the PR3. To be exact Exustar's regular pedal model with the metal plate is the Exustar E-PR3ST.

Pedals hanging.

As most pedals the PR2s hand with the nose up. This way you can slip your foot forward and you'll clip right into the pedals. The key is not to hit bumps or jerk the pedals around, else the pedals will spin.

I didn't change my cleats over so I'm still using the Keo cleats. I have many sets of cleats that I've bought over the years so I have probably 5-8 years of cleat supply on hand.

So far the PR2s have been fine for me. They're just as easy to clip in as my Look Keos but they hold my foot much more securely. I used the pedals both times I raced this year and they've been totally fine.

How To - Clipless Pedal Shoe Fit

So you're looking for a new pair of shoes.

If you've bought them before, if you've been on clipless pedals for a while, it's not that complicated. You figure out if there are any quirks to a new shoe, check out fit, and you buy them.

I find it interesting that even the most fervent online buyer will go and try on (and buy) shoes of a new manufacturer in a bike shop. Granted, once you know a particular shoe fits then you can buy another one (same model/make) confident it'll fit the same.

Just like other shoes, if you're an experienced clipless pedal user buying a different manufacturer shoe, it is critical to try them on. Why do you think they have shoe size runs at Interbike? It's so the dealers can try on the shoes, see how they fit, and get an idea of what sizes to buy. If they don't fit the dealers will scream and the manufacturer will probably change them.

If you're new to the clipless scene how do you check fit?

Believe it or not it's best to have one helper. It could be the person in the shop or it could be a buddy of yours. Make sure they're not squeamish about touching your shoe while it's on your foot. Got it? Okay, head out to the shop.

The reason you need help with the fit is that your shoes perform under different circumstances than when you're standing around trying on the shoes. It's easy to check for fit when you're pressing down on the shoe. This is like when you're standing with that shoe on your foot. It replicates pushing down on the pedal on the downstroke.

HOWEVER...

With clipless pedals you also pull up on the shoe. You're pulling up against the upper of the shoe. Even the original "clipless compatible" shoes by certain manufacturers didn't take into account the pulling up factor - that's why you saw so many riders with either maxed out laces, extra straps or three, etc. The uppers at the time (mid 80s) were designed for toe clips and straps and to have a strap take the upward force, not the shoe's upper.

Nowadays pretty much all clipless type shoes have reasonable uppers that resist the upward motion well. If you're new to clipless you will not know how these shoes should fit or feel. They should be pretty snug on the upstroke, not just on the downstroke.

So how do you check? You have someone hold the toe and the heel of the shoe (on the outside, like grasping just the sole part of the shoe, not holding the uppers) and you lift your foot up flat footed.

 Since I took the pictures I took one side at a time.
This is how your helper should hold the front of the shoe.
Note that the fingers are not holding your foot down, just the shoe.

This is how your helper should hold the rear of the shoe.
Again, note that the fingers are not supporting the foot, just holding the shoe.

A "normal comfortable" shoe will immediately feel loose as you lift virtually your whole foot off the sole of the shoe. You'll be shocked at how easy it is to lift your foot right off the sole.

You should strive for maintaining some contact with the outside of your foot. The inside will lift or unweight and that's normal.

Cinch down on the straps/buckles/wire/whatever and make sure you can achieve a reasonably snug fit on the upstroke.

This is where you check for hot spots and shoe width/narrowness. You may disagree with a seam or something on the inside of the shoe, on the upper. Again, this is something you only feel when pulling up, not when you're walking around the bike shop floor.

Make sure you don't max out the straps just getting the shoe reasonably snug on the showroom floor. Your feet shrink quite a bit when you ride - I find myself clicking a good 2-4 clicks tighter in the first hour of riding and another click or three when I get ready for the sprint. That's maybe 2 cm of tightening - it's a lot. If you have narrow feet the shoe may not accommodate that kind of snugging up.

 You can see that it's possible to adjust the "base" of the strap.
I've clicked it a couple clicks tighter than "factory".

If you look carefully you can see some silver smudges on the ratchets - that's where the buckle engages.
It used to engage up to the last notch, now max is about the 3rd one.

Flex your ankle a bit. You'll do that naturally when pedaling. If you have a really pronounced Achilles tendon you may not like the heel area of the shoe. I personally like a really deep heel cup and I learned that similar models within the same line of shoes ended up with different heel cup depths (Sidi shoes).

The heel of the Sidi. It's not the deepest but it's deep enough. Cutout is for Achilles.

Finally you need to make sure that the shoe works with your pedals. Unless you have bizarre leg issues you won't need massive amounts of adjustment in the pedal, and even if you do there are ways to do it with virtually any shoe (you just have to "modify" the shoe). Therefore I recommend going with a very straight forward, very simple, very easy to deal with pedal - the Looks or the Shimanos.

The ubiquitous Look Keo cleat mounted to the shoe via the ubiquitous "3-bolt pattern".
It's hard to go wrong with a popular standard that works well and is readily available.
On my Sidis there's an adapter plate for different pedal mounting systems, but most shoes don't have that.

You can go into virtually any shop in the country and find cleats and maybe even pedals. You know, like if you fly to Las Vegas for a bike trade show and then realize you forgot your pedals back at your house.

They're easy to get into, they're reasonable to walk on, and they have a reasonable overall weight (some "lightweight" pedals have cleat assemblies that weigh as much or more than the pedal itself). Pretty much every single clipless road shoe out there works with the Look 3 bolt pattern (which Shimano uses too).
