*PHILWOOD* outboard bottom bracket (ITA/aluminum/black)

Phil Wood manufactures Outboard Bottom Bracket (OBB) Cups for integrated spindle and crank systems.

These cups are available in the following thread specifications: British, Italian, Raleigh Super Corsa, French, Swiss, and Chater Lea.

They make OBBs in all threadings to enable those with older, classic frames to adapt to current crank technology.

A threadless (press fit) OBB cup set is available for those that wish to convert older Klein frames that used the pressed-in 6003 bearing bottom bracket shells.

Other frames that use a press fit system with 6003 bearings can utilize this threadless OBB as well.
