Bottom Bracket Socket Adapter
The Birzman Bottom Bracket Socket Adapter fits inside the Birzman Shimano Hollowtech II BB socket, and adapts it for use with Shimano BB9000 and BBR60 bottom bracket cups, which have a different shape than typical Hollowtech II bottom brackets. It's made of hardened steel for durability, and then precision-machined for a precise fit. Birzman backs it with their limited lifetime tool warranty.
