This top - notch adjusting cap tool is designed specifically for installing and removing the adjusting caps of Shimano Hollowtech II crank/bottom bracket systems. Its dual - density screwdriver handle is a game - changer, offering better ergonomics and comfort while helping you control the torque applied to the cap. The precision laser - cut tool bit, crafted from heat - treated tool steel, guarantees strength and long - lasting durability.

Using this tool is easy. First, make sure your bike is stable. Then, place the tool bit on the adjusting cap of your Shimano Hollowtech II crank/bottom bracket system. Hold the dual - density handle firmly and turn it to either install or remove the cap. When using, don't apply too much force suddenly, as it may damage the cap or the tool. After each use, wipe the tool clean with a dry cloth. Store it in a dry place to prevent rusting. If you notice any damage to the tool bit or handle, stop using it immediately and consider getting a replacement.
