Bottom Bracket Adjusting Set

The BBT-6 is an adjustment tool for several of Shimano's cartridge-type bottom brackets. One handle is used to loosen the cartridge's locknut, and the other to make the adjustment. Extra long, coated handles give great leverage for an easy job. At the time (1992-1998), the BBT-6 fit all cartridges except Dura-Ace® and UN models.
