Race Face Carbon Crank Arm BootReplacement plastic crank arm cap for Next, Next-SL and SIXC carbon cranks.
Simple solution for keeping the crud out. Wipes out easy.
I have used these covers on my RF Next cranks for 3 years and the ends of the crank arms look like new (I wish the rest of the arms did). I bought 2 more sets to protect the new XX1 cranks I bought. I wish I had used them on my old Noir crank set, as the ends of those are really beat up, and that is good for carbon.
Do it do it do it! Don't kid yourself with, "I'll be careful" or "I never strike anything." Like Mike A wrote below, "inexpensive insurance." Do it. Great fit on my Sram cranks. Typically great Race Face quality.
I have these on a set of race face sixc carbon cranks, and a set of sram XO Carbon cranks they fit the bill for protection against rock strikes on both cranks perfectly. An inexpensive little insurance policy to protect your very expensive cranks, who wouldn't want that?
these fit my sram carbon xo crankset perfect and do a great job protecting from pedal strikes
