Bottom brackets have some of the highest torque specs of any component found on a bicycle. Despite this, some bottom bracket cups feature tool fittings that allow mere millimeters of engagement, which can be a problem when attempting removal or installation. Solution: the Park Tool Bottom Bracket Tool Retaining System. Used in conjunction with nearly any Park Tool bottom bracket tool, the BBT-RS uses a spring-based tension system to apply consistent, adjustable pressure to the tool, ensuring full engagement with the tool fitting and preventing slippage.
