FSA BB30 Adaptor bottom bracket sleeve which reduces the diameter of a frame with a BB30 bottom bracket to a standard bottom bracket size thus enabling the fitting of a standard 68mm English threaded bottom bracket. The sleeve should be pressed into position with the help of 2 guides (NOT SUPPLIED) and a specialist tool (NOT SUPPLIED).
