Bottom Bracket Socket- OSBB "CLG"

This bottom bracket socket is for use with Colnago's 30mm Bottom Bracket insert, also called T45. It does require the removal of the bottom bracket bearings. It is not compatible with the Ceramic Speed bottom bracket for Colnago.    What makes our bottom bracket sockets unique? Made with the same top shelf aluminum alloy, to the same exacting fit and tolerance as the rest of our socket range, these sockets won't chew up your shiny new bottom bracket. This socket features a threaded boss to allow you to bolt the tool into place when dealing with these exceptionally thin tool interfaces. This is a unique feature to our tools that adds a layer of protection and security to your parts and tools.   Made in Bend Oregon
