Our BB86/92 Outboard bottom bracket will give you all of the same benefits as our press-fit style BBs. The two machined aluminum cups thread together ensuring the bottom bracket remains stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, and really quick bearing replacement.

Directly replaces all OEM BB86, BB89.5 (Not Trek), & BB92 bottom brackets.

BB86-OUT thread-together bottom brackets have known compatibility issues with Quarq powermeter spiders. Click on specific BBs below and review the Compatibility Tab for further information.
