Park Tool BBT-RS Bottom Bracket Tool Retaining System

Park Tool BBT-RS Bottom Bracket Tool Description:

The BBT-RS bottom bracket tool solves a common issue with bike repair and maintenance: bottom brackets have some of the highest torque requirements of any bicycle component and yet, many bottom brackets’ cups only provide a few millimeters of engagement. The BBT-RS is a bottom bracket tool that can be used with almost any bottom bracket tool from Park Tool. It uses a spring-based tension system to supply constant, movable pressure to the tool, assuring full engagement with the tool fitting and preventing slippage. The vast majority of threaded and thread-together bottom bracket standards can be adjusted for operation with the BBT-RS.
