Single Sided Common:

We all know how messy the bottom bracket situation is for modern bikes. We have you covered for almost all of your modern bottom bracket tool needs though. The BB Common was a staple of bottom bracket tools before things got complicated by oversized spindles and press fit. These start as a solid aluminum billet and get precision machined for a nice clean fit. They use a 3/8" square drive for use with your favorite ratchet or torque wrench. We even engrave the default torque spec on them so you don't have to look it up anymore. Starting in 2020 we revised these to be chamferless in an effort to make them work better with extremely thin centerlock lockrings.

Compatibility:
- Early Shimano 10spd gen outboard bearing bottom brackets,
- External spline centerlock lockrings(including Campagnolo),
- Race Face "team" bottom brackets,
- Campagnolo Ultra, Power Torque and Ekar T47 68mm shell width only,
- SRAM GXP,
- Chris King Threadfit 24 bottom brackets,
- Ceramic Speed BSA for 24mm spindles,
- FSA Mega Exo bottom brackets,
- Kogel BSA-24 road and mountain bottom brackets,
- Phil Wood external bottom bracket,
- Wheels Mfg. BSA Threaded 24 and 24/22 spindles bottom brackets.

Dual Sided Dura Ace, Ultegra:

The most unique feature about this tool is the inner nub, that nub in the center of the tool is the same size as the crank spindle. What this does is give you a second point of contact that keeps the tool from camming off of the part when trying to remove stubborn cups.

This dual sided socket is designed to work with the new Shimano DA-9000/XTR-BB93 bottom bracket as well 6800 Ultegra and 5800 105 11spd groups  (BBR-60).

Not compatible with earlier 10spd.
