Phil Wood Outboard Bottom Bracket Sram GXP Adapter

Sram GXP cranksets use a proprietary axle with a diameter of 24mm on the drive side and 22mm on the non-drive side.

This adapter allows you to use your Phil Wood OBB cups with Sram Omnium, Sram S300 or Alpina Track cranksets by removing the stock plastic dust cap from the non-drive side bearing and installing this in its place.

ⓘ A bearing press is recommended for proper installation.
