Race Face Crank Boot Protectors

Great fit on my bike’a cranks.

The Race Face crank boot protectors are a simple yet superbly effective solution for protecting a mountain bike crank arm from damage. What you get are molded rubber-like covers that are nice and thick, offering protection from scratches and impact that clear-type "skins" cannot match. Installation is as easy as removing your pedals, slipping the boots on, then re-installing your pedals. I have used these on SRAM/Truvative X9 and X0 cranksets and they fit perfectly. Two things to note: first of all, there is no mention of a specific left or right side on the products, and you would assume that all crank arms are identical in shape at the ends, but if the Race Face boots don't wuite slip all the way onto your crank arm, swap the left boot for the right boot and they should be centered and all the way on (I experienced this with both cranks I tested). Second note - upon reading other reviews here, some say they fit other brand/model cranks, some say they don't - but if you take a look at the Race Face website, they actually have a list of what cranks they know are compatible: (from Race Face website) Fits: Race Face: Next/Next SL Sixc Respond Sram: XX XO Noir FSA: Gravity Gravity Lite Shimano: Saint Notice though that my X9 and X0 crankset is not listed - yet they fit perfectly - so if you do not have any of the cranksets listed the only way you can find out is to try them. Not that big of a deal to experiment since it's only $9 a pair, which is a value considering you are protecting your $250-up crankset from rock strikes and damage.

RaceFace makes three different boot covers for the following cranks types. I did the resarch to make this east for your. Take a few minutes to read this information.

Also, these crank boot covers have the word “NEXT” printed on them, whereas the other boots only have RaceFace on them. 2. CARBON CRANK BOOTS (this is the version you will receive if ordering here). This is the MEDIUM SIZE boot cover.

Although, these crank boots did not fit my cranks from this order, I did purchase a pair from another vendor that sold the correct size (small) for my cranks. However, they are all made from the same material, so I am giving five stars for quality of product. I installed the Alloy Crank Boots (size small) on my Stumpjumper which has Aeffect cranks. They fit good. The only thing I noticed is that the hole were you put your Allen key is a little off, but the boot cover is playable enough that I was able to install it with no problem.

Might not fit your cranks! I was looking to find some crank boots to put on my 2021 Turbo Levo SL with Praxis carbon cranks. These boots did not line up with the cranks. However, they did line up with my Sram GX transmission aluminum cranks. Nice thick material, will protect the crank end from scrapes and scuffs. Also fit my Amflow aluminum cranks. As long as you do not have high end carbon cranks, excluding Race Face, they should fit fine!

I have a bad habit of hitting rocks and logs with my bike cranks. They were starting to look like they had been through a cheese grater. These Race Face Crank Boot Protectors were exactly what I needed. They slipped on snugly and look great. Now, when I inevitably hit something, I hear a satisfying thump and know my cranks are safe. They're a small investment that protects a much more expensive part of my bike. If you're a clumsy rider like me, you need these. They've saved my cranks from countless scratches. Five stars for saving my bike from my own terrible riding habits.

These are the best of the bunch. Actually made of plastic and stay put unlike the the rubber type.

The quality is fine. What I am running into with Race Face is their colors don’t match across their own products. I bought Race Face Chester pedals in blue and they don’t match in color to these Race Face crank arm protectors. I really wish the colors matched.

Easy to install. Offers good protection against rock strikes. One size fits most. I prefer the more secure fit of the All Mountain Style Crank Defenders.
