BBT-41x16-24 - Pro BB Cup Socket installation tool. 41mm by 16 spline cup tool with an inner bearing guide insert for cranksets with 24mm bearings (Shimano).

This tool is designed for the professional removal and installation of Maxhit BSA 24 & Shimano FC-25 BB cups with 24mm ID bearings for Shimano cranksets. The 41mm by 16 tooth spline cup matches Maxhit BSA24 and all Shimano FC-25 BB cups.

The updated design of the line of Enduro BBT Pro Cup Socket tools 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 (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.
