Carbon crank arms are one of those parts that look tough but hate direct hits — the end of the arm sits low enough to catch rocks on pedal strikes, and repeated shoe rub against the inside face slowly grinds through the clearcoat. SRAM's Crank Arm Guards in this SKU (00.6118.444.000) are made specifically for XX1 and X01 Eagle cranks , and they wrap the vulnerable outer end of the arm to take the abuse instead of the carbon underneath.

The guards install over the end of each crankarm and cover the section closest to the pedal — the zone that takes the worst of it from rock strikes, log crossings, and grounded pedals on techy climbs. This is a pair of SRAM XX1/X01 crank boots that works with 11-speed or 12-speed Eagle cranks , so if you've been running the same set of XX1 or X01 arms across drivetrain generations, they're covered here.

Fitment is specific: these are shaped for the carbon XX1 and X01 Eagle arm profile. If you're on GX carbon or an alloy Eagle crank, this isn't the right guard — SRAM makes a separate part (00.6118.321.000) for those. It's worth confirming which crank you have before ordering, because the guards will not seat correctly on the wrong arm shape.... Read More
