Wheels Manufacturing Outboard Bottom Bracket

The outboard bottom brackets from Wheels Manufacturing allow Sram DUB MTB and road cranksets with a 29 mm axle to be fitted to 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 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 within 10 / 1,000,000. The ball material, 52100 high-carbon chromium alloy, is extremely robust and specially hardened. It is also polished to a high gloss.

Sram DUB crank axles 29mm:

SRAM has developed its own axle standard for the DUB cranks. The SRAM DUB cranks have an axle diameter of 29 mm and are only compatible with bottom brackets designed for DUB cranks.

BBright bottom bracket shells:

The BBright bottom bracket shells have a width of 79 mm and a press-fit dimension of 46 mm for the bottom bracket. These bottom brackets are press-fitted. With Wheels Threaded or Cane Creek bottom brackets, the bearing cups are screwed together and thus pulled into the bottom bracket shell. This is the significantly more durable assembly, as the bearings are additionally secured by the bearing cups.
