RacrankUniversal Crank Boots, Crank Protectors for Bicycle Cranks, Crank Boot Protectors for Mountain Bike Road Bike, Pack of 2

These fit my 2022 XTR crank arms no problem and have held up well over many rides.

These fit tighter and the pedal thread holes line up better than the brand name SRAM boots they replaced on my Truvativ Carbon Descendant crank arms. I have had no problems with them slipping around and there are no visible gaps around the edges of the arms for dirt to get in. They are at least as durable as the SRAM boots, if not stronger. I have hit plenty of rocks and the boots are barely scuffed. I now have these on all of my mountain bikes.

I bought these without knowingly for sure but confirmed that they fit very nicely on sram GX cranks. No cutting, heating or anything needed to get them on. They have a slightest of play in them on the crank but only if you specifically move them around. The plastic seems very durable and overall I’m very happy with the fit!

I was a little nervous ordering these as you never know if they will fit. They slide on easily but tight enough to feel secure On SRAM X01 carbon cranks. They seem to slide on a little farther than you think would work but with my deity deftrap pedals the pedal post will slip past and under the little bit of protector that overhangs the threads. I have not tested their durability and or protectiveness yet. But they seem like little pieces of plastic that will hopefully disperse any impact energy.Update - I have a few rides with these on and did manage to catch the cranks a couple times. I added a photo showing the marks on the boot and the crank under it is undamaged. So it looks like they do provide some protection.

I had to wrap some electrical tape around the crank arms so that these would fit snug. They should be fine but we'll see.
