BB30 External ABEC-3 SRAM Center Cup

Two machined aluminum cups thread together, keeping the bottom bracket stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, longer bearing life, and a super-fast bearing change.

Specifically designed to install 22mm/24mm spindle diameter cranks (SRAM / Truvativ GXP) in BB30 frames (42mm ID BB shell) without adapters.
