Description

The PARK TOOL BBT-147-12 Bottom Bracket Tool is a robust tool precision-machined from 4140 steel for removing and installing 12-notch threaded bottom brackets, including Chris King® ThreadFit™ T47 and ThreadFit™ 30.

Its extra-deep body accommodates wide spindles, while its low-profile walls engage recessed lockrings. Three drive options — a 3/8" square drive, 1" hex drive and 36 mm wrench flats — help tackle even the most stubborn components.

Compatible with a wide range of T47 bottom brackets: BBInfinite® T47, Chris King® ThreadFit™ (30, T47, T47 24x, T47 30), Hambini T47, Rotor® T47 External 30 mm, as well as Rotor® BBright®, BB30, BB386EVO and PF30 thread-together systems.

Integrated threading allows use of the BBT-RS retaining system or GPS guide pins (sold separately) for greater stability during use.

⚠️ Not approved for use with powered impact tools.
