Cervelo developed the BBRight standard to gain stiffness through an asymmetric bottom bracket shell—wider on the drive side where pedaling loads concentrate. The design worked, but it also created a compatibility puzzle. Standard PF30 bottom brackets don't fit the 79mm shell width, and finding quality replacement options for BBRight frames often means hunting through limited inventory or settling for whatever's in stock. Wheels Manufacturing solves this with a purpose-built BBRight bottom bracket that fits the standard directly without adapters, giving Cervelo owners a reliable upgrade path when the original equipment wears out.

The thread-together design addresses the creaking that eventually develops in most press-fit installations. Two machined aluminum cups thread against each other through the BB shell, clamping the frame between them rather than relying on interference fit alone. This mechanical lock stays tight regardless of temperature changes, humidity shifts, or material relaxation over time—factors that gradually loosen conventional press-fit cups until they move under load and generate noise. When the bearings need service, you unthread the cups rather than pressing them out, which means no risk of enlarging the shell bore with repeated installations—a real concern on carbon frames where shell damage can be expensive or impossible to repair.

Inside the cups, Enduro ABEC-3 bearings handle the loads. These are standard 24x37mm cartridge units available from any well-stocked bearing supplier, so future replacements don't require proprietary sourcing or long lead times from a single manufacturer. The bearings spin smoothly with good durability for typical riding conditions—if you're not chasing marginal friction reductions, ABEC-3 delivers the performance most riders need without the cost premium of angular contact or ceramic options. Crank compatibility covers 24mm spindle diameters, which includes Shimano Hollowtech II, RaceFace EXI, and most other cranks using the same dimension. One note on FSA: their MegaExo spindles can measure anywhere from 24.00mm to 24.07mm, and if yours lands at the upper end, the bearing bores won't clear the spindle. Wheels Manufacturing sells replacement bearings sized for 24.07mm spindles if that situation applies.... Read More
