Wheels Manufacturing Outboard Thread Together Bottom Bracket – BBright

Performance & Use Case
The Wheels Manufacturing BBright Outboard Bottom Bracket is the upgrade replacement for any Cervelo BBright frame. Where OEM bottom brackets wear out and need full replacement, Wheels Manufacturing’s design uses serviceable Enduro bearings that can be replaced when worn – extending the bottom bracket’s working life and reducing waste. Moving the bearings outboard adds drivetrain stiffness and removes the frame-tolerance issues that affect press-fit alternatives.

Construction & Materials
The shell is machined in the USA from aluminium for precision tolerances and lasting durability. Double lip-sealed Enduro bearings keep water and grit away from the bearing surfaces. Angular contact bearing variants disperse load more evenly than standard cartridge bearings, particularly relevant for SRAM cranksets under hard pedalling.

Compatibility
Designed specifically for Cervelo BBright framesets. Two spindle-compatibility options cover Shimano Hollowtech II (24mm) and SRAM GXP (22/24mm) cranksets. Each spindle option is available with standard ABEC-3 or angular contact (AC) bearings. Select the variant that matches your crankset and your performance preference.
