Review on Park Tool BBT 22 Shimano Cartridge by David Estevez

Revainrating 4 out of 5

Use a screw to prevent the tool from slipping off.

Works well, all these tools are the same. Tool slippage under torque is a Shimano interface design issue, not parking. To prevent slipping, hand tighten the tool with a 45mm 8x1 bolt. Install a washer, 24mm or smaller. It needs a square hole, yes, but just get a 1" deep socket if you're using a torque wrench. Pedros makes a bolt tool, but a bolt and washer is less than a dollar.

Pros
  • Generates trust
Cons
  • Everything is fine
