Bottom Bracket Socket- OSBB "CK"

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.
