*PHIL WOOD* obb adapter (gxp/aluminum)

The OBB Adapter from Phil Wood, a long-established bicycle component manufacturer based in San Jose, California, has been pursuing the ultimate in durability since 1971.

Phil Wood has earned a strong following among riders around the world, from professional track racers to hard-working bicycle messengers.

This adapter is required when using a crankset with the SRAM GXP standard.

By pressing it into the non-drive-side cup of an OBB for Shimano HOLLOWTECH II, it converts the inner diameter from 24mm to 22.2mm.

The machining is exceptionally precise, allowing the adapter to fit perfectly and securely.
