The ends of your crankarms don't have an easy life. Between rock and root strikes and flying trail debris, the trail is always gunning for them. You can give them a chance to fight back and add a touch of color to coordinate with your bike with the INPower Bumper Set from Rotor. Designed to keep your cranks scratch free, these bumpers slide on to your KAPIC or InPower Cranks for additional protection and are low profile for a snug fit that stays put while riding.
