Product details

Park Tool BBT-79.3 bottom bracket wrench

The Park Tool BBT-79.3 bottom bracket wrench is designed to install and remove specific threaded bottom brackets with a 12-notch interface. Precision CNC-machined aluminum provides engagement with the compatible component; the anodized finish makes the tool easy to identify. The 3/8" drive allows use with a ratchet or torque wrench, making it suitable for workshop or in-bike maintenance tasks.

Listed standards include SRAM BSA DUB, Race Face Cinch, Rotor BSA30, Zipp Vuma and Hawk Racing BB3086. The integrated thread allows use with the Park Tool BBT-RS retaining system, sold separately, which applies adjustable tension to keep the tool in place during use.
