Unior Bottom Bracket Sockets

All models of bottom bracket sockets are precision CNC machined tools for installation and removal of different external bottom bracket cups. They are made of aluminum billet and anodized red for durable finish and precise fit, that won´t damage aluminum external bottom bracket cups. Knurling on the side of the socket creates better grip when threading cups by hand, meanwhile 1/2" square drive makes it easy to use with torque wrenches, ratchets and fixed handles.

Like all of Unior’s tools, bottom bracket sockets are proudly designed and manufactured in Slovenia.

Sockets may vary slightly on external finish from the images as new stock arrives

The UT-627621 will also work with the LEVO SL motors for removing the lockring/spider
