The Truvativ/SRAM Team GXP is a threaded bottom bracket for English/BSA 68 and 73 mm frames and GXP cranks.

What it's for

Use it to install or replace the bottom bracket on a bike with a SRAM or Truvativ GXP crankset.

How it works

Gutter Seal: a seal design that keeps water and grit out of the bearings with low drag.

GXP: SRAM's 24 mm external bearing system. Sealed cartridge bearings sit in aluminum cups outside the frame shell.

• Does not fit: DUB cranks, PressFit or BB30 frames
