Phil Wood & Co Outboard Bottom Bracket (@philwoodco)


Outboard Bottom Bracket Cups

We manufacture 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.
We 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.

SRAM / TRUATIV Adaptor

Truvative and SRAM cranks use a unique bearing on the non-drive side. We have manufactured an adaptor that enables one to use a standard OBB cup with Truvative and SRAM cranks (middle image). At this time Campagnolo cranks are not currently compatible. Cmapagnolo uses a center bearing on their crankset, this interferes with our bottom bracket.

Replacement Bearing Dust Covers

We offer two sizes of replacement outboard bottom bracket bearing dust covers. We have a standard dust cover which is good for everything except Shimano and a medium dust cover which is good for newer Shimano (Dura Ace, XTR) parts.
