These will undoubtedly last through the toughest rock gardens in Arizona. I've had numerous moments of accidental impacts that almost lifted the bike off the ground. Even still, there are no punches or tears on these crank arm booties. That's very impressive, in my opinion! If you're like me, you may have not known about these until after sustaining some scratches and gouges on the crank arms. It's still not too late. For what it's worth, these will do a great job and will absolutely hold up through the test of time. Also, these crank arm boots may actually end up giving you the confidence that you need to learn how to ride up / down/ around those daunting rocks?

Got these to protect my Race Face Next SL (full carbon) cranks. My previous aluminium crankset picked up a few scrapes at the end of the arms on the local rock gardens, so I wanted some protection for the new cranks. A couple of months of riding and a few rock gardens later and the boots are getting thrashed. First they got loose and let in a ton of grit which scuffed the ends of the arms (not a deal breaker), and then picked up some tears. I'm not an expert at the rocks - but I don't recall any major hits. I figure I have another month before I have to replace these. Long story short, I'd say these are essential to protecting your cranks (particularly carbon), but - they are a wear item that you'd probably have to replace a couple of times a year.

These installed fairly easy, I just warmed them up with a hair drier and tapped them onto the crank arm with a small mallet. I have hit rocks with them and so far they are holding up nice. If you want to protect your crank arms from pedal strikes you need these.

...A tight fit on my Specialized cranks (2014 S-Works Camber) but they are there to stay and protect the carbon cranks I’m running. The Large size ones I had on previously were too big and one of those fell off because of size.

These rock. Got a brand new rocky mtn pipeline and decided to install these before my first ride. Ride into rock gardens as fast as you want, with these on, your cranks will look good as new.
