Wheels Manufacturing Outboard Bottom Bracket

The Outboard bottom brackets from Wheels Manufacturing allow Sram and Truvativ GXP MTB and road cranksets with a 24/22 mm axle to be fitted to frames with asymmetrical Pressfit30A bottom bracket shells, e.g. Cannondale with a 46 mm press-fit depth and a width of 73 mm.

PressFit 30A, asymmetrical, bottom bracket shell:

Unlike standard PressFit 30 bottom bracket shells, the BB30A shells are asymmetrical. The bottom bracket shell width is 73 mm and is narrower on the drive side. Consequently, standard PressFit 30 bottom brackets do not fit, nor do BB30 road bike cranksets. The axles of BB30 road bike cranksets are too short for a 73 mm installation dimension.

Sram GXP axle system:

The Sram GXP crankset system features different axle diameters. The outer diameter of the axle on the drive side is 24 mm and 22 mm on the left side. GXP-compatible bottom brackets are required for this.

Wheels Threaded Outboard:

Unlike other press-fit bottom brackets, the Wheels Manufacturing outboard bearing cups are screwed together. This has the major advantage that the bottom bracket shell sits very firmly and absolutely parallel within the frame. This ensures a long service life for the bottom bracket. The bottom bracket cups are made from high-strength aluminium.

Wheels Enduro ABEC3 ball bearings:

The Wheels Enduro ABEC3 ball bearings offer very high precision. The balls are twice as round as standard industrial bearings, with a roundness tolerance of 10 / 1,000,000. The ball material, 52100 high-carbon chrome alloy, is extremely robust and specially hardened. It is also polished to a high gloss.
