SRAM GXP cranksets run a 22mm non-driveside spindle, narrower than the 24mm bore most bottom bracket shells and adaptor systems are built around. The CEMA SRC-BB-A0012B adaptor kit bridges that gap, converting a 24mm bottom bracket bearing bore down to fit SRAM BB3024, RBB3024 and BB30A24 shells — letting you run a SRAM GXP crank in a shell that wasn't originally speced for it.
Manufacturing defects are covered under CEMA's warranty terms. Return the kit to Tune Cycles and we'll manage the claim on your behalf. This is in addition to your rights under the Australian Consumer Law.
