Park Tool BBT-RS bottom bracket wrench holder

The Park Tool BBT-RS is an ingenious accessory designed to ensure a secure grip on bottom bracket wrenches, even when the tool’s notches are shallow. Thanks to its adjustable spring system, it applies constant pressure, preventing slippage and ensuring precise and reliable installation and removal. Compatible with most threaded, cartridge or tapered bottom brackets, it adapts to a wide range of standards thanks to its M8 x 1.0 shank and its double-sided M12/M15 threaded nut. The M15 adapter also allows the use of Park Tool aluminium tools with the corresponding thread, for increased versatility. Simple to install and robust, it optimises safety and durability during workshop repairs. The BBT-RS provides a reliable anti-slip solution, thanks to its adjustable spring which holds the tool firmly on the bottom bracket shell, even if the shell has shallow grooves. With its wide compatibility, including threaded, cartridge and tapered bottom brackets and numerous standards (M12/M15), it fits the majority of models and can be used with almost all Park Tool tools. Easy to use, it allows for safe assembly and disassembly whilst preserving the integrity of the components, making it the perfect ally for demanding workshops.
