The BSA30 Bottom Bracket is the solution for using a 30 mm crank spindle with your English threaded frame. We have options for  Black cups and steel or ceramic bearings or Red cups with a choice of ceramic bearings. This bottom bracket comes with the tool needed for its installation. Do take note if your crank will work with the frame/bb combination here. Some spindles are not long enough to make this work. Known cranks that DO work include: Rotor 3D+, 3DF, and 3D Flow, The Quarq cranks - Elsa and Riken, as well as and BBright crank or BB386EVO crank. Call us for compatibility questions. (Includes ROTOR branded cups and Enduro bearings)
