Hope’s GXP Bottom Bracket Conversion kit allows the use of GXP cranksets in any of Hope’s bottom brackets designed to accept 24mm spindles.
GXP cranksets have a spindle that tapers from 24mm on the drive side, down to 22mm on the non-drive side. This conversion kit steps down the non-drive side cup to support the 22mm diameter of the GXP crankset spindle.
