Shimano Ultegra FC-6800 Crank Arm Fixing Bolt

The Shimano Ultegra FC-6800 Crank Arm Fixing Bolt is a small but critical component for secure crank arm installation. Machined to precise Shimano specifications, it threads into the left crank arm to preload bearings and keep your Hollowtech II crankset running smoothly. Over time, fixing bolts can strip or wear, so replacing with a genuine part ensures safety and drivetrain efficiency. Compact and durable, it’s an essential spare for any rider running Ultegra 11-speed cranks.
