UNIOR Bottom bracket cup socket 1671.BSA30 627621

All bottom bracket socket models are CNC-machined precision tools for installing and removing various external bottom bracket cups. They are made from billet aluminum and anodized red for a durable finish and a precise fit, and will not damage external aluminum bottom bracket cups. The knurling on the side of the socket provides a better grip when threading the cups by hand, while the 1 / 2 square drive makes it easy to use with torque wrenches, ratchets and fixed handles.
