This version of Phil's buttery-smooth, long-lasting outboard bearing BB is compatible with cranksets having a hollow 24mm spindle (like Sugino 75 Direct Drive & DD2, and Andel Deluxe).
Aluminum cups available in 8 colors, stainless steel is polished silver.
If you have Omniums or any other Sram GXP-style crankset, you need to buy the version we sell with the GXP adapter installed, or purchase the Phil Wood GXP adapter separately (which we also sell) and install it yourself.
