This bottom bracket socket is for use with Chris King's T47 Bottom Bracket.

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 feature unique to our tools that adds a layer of protection and security to your parts and tools.
