Unior spanner for bottom bracket T47 1671.T47

All bottom bracket sleeve models are precision CNC-machined tools for the installation and removal of various outer bottom bracket bearings. They are made of billet aluminium and red anodised for a strong finish and perfect adhesion, which does not damage the aluminium outer bottom bracket bearings. The knurling on the side of the sleeve ensures a better grip when inserting the bearings by hand, while the 1/2˝ 4-point control sleeve makes this tool easy to use with torque spanners, ratchets and fixed handles.

Features

The T47 double-sided bottom bracket sleeve has a 16 and 12 Notch interface with interchangeable adapter to cover all different T47 bottom bracket standards.
