Product Description The - for FSA MegaEvo The BBS4816 bottom bracket tool from Wolf Tooth Components is primarily compatible with FSA MegaEvo bottom brackets, but also with models from Wheels Manufacturing. It is important that the bearing cups have 16 teeth and an outer diameter of 48 mm. Accordingly, the tool has 16 notches for more grip when screwing on the cups by hand. It can be combined with a 3/8" square drive ratchet or a 1" torque wrench. Thanks to its magnetic steel inserts it also fits perfectly with the Pack Wrench. Like all Wolf Tooth bottom bracket tools, the BBS4816 is CNC machined to ensure particularly high quality. As a bonus, an 8-slot dust cap wrench is integrated, which can be used to loosen the crank bolt of Shimano cranks.
