Bottom Bracket Socket - 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.
