Park Tool BBT-RS Bottom Bracket Tool Retaining System

Park Tool BBT-RS Bottom Bracket Tool Retaining System

• 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

• The BBT-RS can be configured for use with the vast majority of threaded and thread-together bottom bracket standards and features an M8 threaded rod and a double-sided adapter nut with M12 and M15 threads, allowing it to thread directly into any compatible cartridge bottom bracket

• The M15 adapter can also be used to install any of Park Tool's nine aluminium bottom bracket tools, all of which feature integrated threading for use with the BBT-RS

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.
