Product Overview
This is the tool you need to remove or install the IRD bottom brackets we sell, as well as many other square taper, ISIS or Octalink BBs with 20-notch cups. This tool also fits the lockrings found on RaceFace Cinch cranksets.
You'll also need a 3/8" drive socket wrench or a large adjustable wrench. We prefer to use the adjustable wrench as it allows leverage to be applied very close to the BB cups, reducing the possibility for the tool to twist and slip.
