This tool is designed for the professional removal and installation of T47 & Torqtite BB386 & PF30 BB cups with 30mm ID bearings. The 52mm by 16 tooth spline cup matches most T47 BB cups as well as Enduro Torqtite cups.

The updated design of the line of Enduro BBT Pro Cup tools Socket feature a unique design that allows you to switch between 24, 29 and 30mm inner guide inserts or a universal insert, depending on the application. The inner guide inserts simply snap-in to keep everything straight while installing and removing BB cups. Each snap-in insert features a 3/8 inch drive for use with a torque wrench or breaker bar. Spline cup options include: 52x16 (T47 & Torqtite BB386 and PF30), 46x12 (BSA 29&30), 44x16 (BSA24/FC32) & 41x16 (Maxhti BSA24/FC25). The entire tool is precision manufactured of the same aluminum alloy (6061 T6) as our BB cups to ensure secure, no-mar cup installation and removal.
