Those are worrisome developments...the failure rate is too high for it to be chance alone (it seems).

In the old locked thread on this topic, RustyChain wrote, "I had a two sets of Keo pedals with each having over 10000 miles on them and working great. Look recalled them and replaced the spindles and bearings free." Perhaps Look fixed the problem(s) in the 2012 model. I'm guessing that might be the case as, according to the blurb for the pedal on the CC web site, "(Look)...redesigned (the) composite pedal body. It's quite different than the Keo, utilizing the new Keo 2 design...The result of the design change is 31% greater surface area than the old Keos...The axle is new as well..."

However, based on the description, its hard to tell if this refers to a re-design of an older model pedal (the Keo) or a re-design of the Keo Blade. Any comments or insights on that? My use, so far, is too limited to reach any kind of conclusion.

My Keo Max pedals developed bearing play, would squeak a lot and I tolerated them until one day I went to sprint and my left foot aggressively unclipped, my toe smashed into the road taking out a big chunk of my shoe and I was lucky to keep the bike upright and not crash. I noticed the rear plastic clip/spring area had worn enough to let my foot unclip. Pedals were only 12 months old.

Gone back to shimano pedals, Durace carbon ones, perfect bearings, tight engaged clip in that I can hammer with confidence and the cleats last for ages.

Not sure why people put their safety on the line with look pedals, they're not safe imo and can't take the abuse, unless you're a pro rider who can get new pedals every few weeks.

Why would you buy anything Contador has his hands on?

But to be fair, you can find the Keos for fairly cheap..

DA pedals cost more and it is better to buy it from an authorized retailer to get the 3 year warranty.

Hi folks - I just stumbled across this thread. I too am a victim of Keo Blade failures; in fact, I've had the same failure occur twice within the past year. Both of the failures occurred in the carbon "tension spring"...similar to what some others have also pointed out. Both times this occurred on my right pedal, which makes sense since that's the side I click out of when I come to a stop. The only other thing that makes me different from most riders is that I release via "toe out" vs. "heel out"...a little hard to imagine why that would make a difference, though. Has Look officially acknowledged to anyone that they have a quality control issue here?

Hi

When mine broke at the back end and I contacted LOOK they replied without hesitation to return it to the dealer for replacement and that yes, this was indeed (if not common) a known issue and that theyd replace them without question. I inquired firther about it and I was told that the newer versions (2012) were "reinforced" to avoid such failures, no idea of that is actually true or not but thats what I was told. The "newer"/reinforced version are those without the LOOK logo on the bottom, the previous versions all have LOOK on white on the bottom of the pdeal-body. Again, no idea if this version was actually reinforced, but they did change something I think or else why would they stop stamping the logo... I told the rep I like the logo and he concurred and said there was some dispute within the company about the aesthetic change. Thus, my belief (pure faith) is that they did something to correct the breakages at the back of the pedal and also changed the "look" of the pedal or else why would they just stop printing their logo? Corporate-branding seems to be at least as important to a company as function so to me one-less LOOK logo must signal SOMETHING... lol.
Lastly, my dealer at the time did not hAVE the newer versions so my replacement was the same version of pedal as the one that broke, been riding it since then with no problems but I switch between 2 bikes now so maybe less time on it and will take longer to fail again. Would love to keep using them as I really do like the way they feel and function overall... fingers are crossed.
