Race Face Crank Boots Alloy RED for Alloy CRANKS A10068RED

Perfect fit for my Shimano XT M8000 hollowtech II crank arms! Also fits my SLX Shimano crank arms so I think this is the size for most Shimano cranks based on what I can tell. Nice product, definitely looks cool!

These boots fit perfectly over my RaceFace Aeffect crank arms. So far, they have not had to protect anything, but I now have peace of mind while riding, knowing that my brand new bike is going to have one less area with dings! Check the fitment on RaceFace.com, as they offer two sizes and I initially purchased the larger size, which was too big.

Fit perfect & snug for my 2021Trek Slash 7! Gracias Amigos, they came in handy when I went to China camp for some all day riding, I bapp’d them more then once on tree roots & rocks and thought I tore them off but they help up! 🤙🏼

Good looking crank boots. Match my bike. They are a little small for my shimano acera crank arm. I had to trim a little bit. But they fit and look good now.

I bought these because I recently purchased an NX groupset. Although this groupset is not a top of the line or more expensive one, $400 is still a lot for me. So I wanted to protect my little investment.These work great. I saw a sharp rock that I always try to avoid but since I had these I actually wanted to test them and slightly tap the rock with my protected crankset. It worked like a charm and there was only a scuff mark on the boot. I haven't intentionally hit rocks anymore but it is good to have them protected.I recently went on another ride and my tire scooped up some rocks and hit the crank arm and this is where I wished I had the sleeves too. Oh well, the boots did the trick but if you want added protection, get the sleeves for the crank arm too.

Made for RF cranks but fit on Shimano cranks too. This fit my basic Deore cranks snugly. They needed just a bit of heat to push on. SLX and XT cranks should fit the exact same. The hole isn't perfectly lined up, so you'll need to give it a little nudge with a flathead or pick to seat the pedals, but it's not a big deal.

RaceFace makes one billion different sizes of these things and it is completely unclear which ones go with which cranks!

They fit my deore cranks but a bit small as far as the holes in the back lining up. Other then that they seem like they will protect the arms from hits and scrapes
