Bottom Bracket Socket T47
All bottom bracket sockets are precisely CNC‑machined for installing and removing various external bottom bracket cups. Made from billet aluminum and anodized red for a durable finish and precise fit that won’t damage aluminum bottom bracket cups. Knurling on the side of the socket provides better grip when threading cups by hand, and the 1/2" square drive makes them easy to use with torque wrenches, ratchets, and breaker bars. • The double‑sided T47 bottom bracket tool features both 16‑ and 12‑notch interfaces with an interchangeable adapter to cover all T47 bottom bracket standards.
