Wheels Manufacturing Outboard Bottom Bracket

The outboard bottom brackets from Wheels Manufacturing allow Sram MTB and road cranksets with a 24-22 mm GXP axle to be fitted into frames with BBRIGHT bottom bracket shells measuring 79 mm in width and with a 46 mm press-fit depth.

Unlike other press-fit bottom brackets, the Wheels Manufacturing cup sets are bolted together. This has the major advantage that the bottom bracket shell sits very securely 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. For optimum durability, Wheels MFG manufactures its own bottom bracket cups for each bottom bracket shell, with the correct offset, even if the press-fit depth is the same as for 386EVO, Pressfit 30 and BBright bottom brackets. This ensures that the bearings are positioned as far out as possible and the crank axle is supported as effectively as possible. Other manufacturers use spacers for the different installation widths, which is not quite as ideal.

Wheels Enduro Angular Contact Ball Bearings:

The Wheels Enduro ABEC5 angular contact ball bearings are specially designed for use in hubs and bottom brackets. Whereas in standard radial bearings only 3 or 4 balls are loaded simultaneously, in angular contact ball bearings all balls are loaded evenly. This is why this type of bearing is also known as a full-contact bearing. This distributes the applied force across the entire bearing, reducing friction and wear. The balls in these bearings are manufactured with extreme precision, with a tolerance of just 10/1,000,000 – twice as precise as standard industrial bearings
