BBT-46x12-30 - Pro BB Cup Socket installation tool. 46mm by 12 spline cup tool with an inner bearing guide insert for cranksets with 30mm ID bearings.

The updated BBT Pro Cup Socket tools all feature a unique design that allows you to switch between 24, 29 and 30mm 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 (Maxhit 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.
