Instead of the plastic tool Shimano includes with its Hollowtech II crank/bottom bracket systems, use Park Tool's BBT-10 Crank Adjusting Cap Tool to remove and install the adjusting cap. Made from investment cast steel, the BBT-10 provides strength and leverage to easily remove seized caps or make small adjustments.
- Easily adjust your Hollowtech II cranks
- Strong, durable, investment cast steel
- Compatible with an 8mm hex for added leverage
- Built in safety plate hook
