Review on 🛡️ Ultimate Protection: SRAM Crank Arm Boots for Unbeatable Performance by Bill Schlag

Just got it in the mail yesterday and immediately mounted it on my new XO-1 carbon crank. Fits perfectly. As another buyer mentioned, applying a small amount of lube (I used Park Tool Poly lube) before installing it in the guard will help ensure it fits properly and protect the crank itself from the inevitable dust and grit that gets into the inside. guard. They fit snugly though, so I would expect this to be minimal. However, it never hurts to take the right precautions. Since they are made by SRAM for their cranks, they fit perfectly. It is great.
