Wheels Manufacturing Outboard Bottom Bracket

Wheels Manufacturing’s Outboard bottom brackets allow Sram MTB and road cranksets with a 24-22 mm GXP axle to be fitted into frames with BB30 bottom bracket shells featuring a 42 mm press-fit depth and widths of 68 and 73 mm.

SRAM cranksets with the GXP axle system have a narrower axle diameter on the non-drive side than Shimano Hollowtech II cranksets. Therefore, these bottom brackets are only compatible with SRAM GXP cranksets

Wheels Zero Ceramic Angular Contact Ball Bearings:

The Zero Ceramic Enduro bearings feature high-end Type 3 ceramic balls with stainless steel bearing cups. These ceramic balls are the roundest manufactured for civilian use. The bearing cups are made from pure silicon nitride material with extremely high density and a uniform surface. They also weigh 60 per cent less and are seven times harder than steel balls. Angular contact ball bearings have raceways in the inner and outer rings that are offset relative to the bearing axis. They are designed for applications that must withstand combined loads, i.e. simultaneous radial and axial loads.
