Phil Wood bottom brackets are absolutely legendary. While others claim to offer the ultimate bottom bracket, only Phil Wood has actually done it.

This bottom bracket features Phil's 17mm proprietary U.S. produced heat-treated stainless steel spindle. This special spindle provides you with maximum durability and an absolute minimum amount of flex. The Phil Wood sealed cartridge bearings have the same seals as those used in submersible pump bearings. This integral one piece shell seals out contamination, keeping your bearings super smooth. Phil's unique trademark cupped flats provide superior crank arm retention.

For compatibility, Phil Wood bottom brackets are built with cartridges that have standard offsets. Phil's cartridge cups provide an additional 5mm of chain line adjustment so you can get your chain line just right. The cartridge cups are available in British, French, Italian, and Swiss threading so you can install this Phil Wood bottom bracket on practically any bike. Chater Lea and Raleigh Super Corsa cartridge cups are also available.

American made in USA (U.S.A.)

Please note that this BB also requires Phil Wood cartridge cups which are sold separately. Please specify the threading you require.

You'll also need a Phil Wood portable installation tool and wrench.

Additionally you can also add Phil Wood Cartridge Cap Mudguards, while these are not essentially we highly recommend them for keeping the bearings in the best possible condition and adding a splash of color to your ride!
