The PARK TOOL BBT-135-12 Bottom Bracket Tool is a robust tool precision-machined from 4140 steel for removing and installing certain 12-notch threaded bottom brackets, including Praxis Works® M30 models.
Its extra-deep body accommodates the widest spindles, with thin walls at the engagement point for recessed lockrings. Three drive options — a 3/8" square drive, 1-inch hex drive and 36 mm wrench flats — help tackle even the most stubborn components using the tools available in your workshop.
Compatible with 12-notch bottom brackets with an outside diameter of 48 to 50 mm and an inside diameter of 46.3 mm, including Praxis Works® M30.
Integrated threading also allows use of the BBT-RS retaining system or GPS-1 guide pins (sold separately) for greater stability.
