Wheels Manufacturing Outboard Bottom Bracket

The Outboard bottom brackets from Wheels Manufacturing allow MTB and road cranks with a 30 mm axle to be fitted into frames with BBRIGHT bottom bracket shells measuring 79 mm in width and with a 46 mm press-fit depth. These bottom brackets are compatible with cranksets featuring a 30 mm axle system, such as FSA BB386, Race Face Chinch 30, Rotor 30 and Sram BB386Evo cranksets. These cranksets have longer axles than BB30 cranksets. BB30 cranksets cannot be fitted to these bottom brackets.

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 dimension is the same as for 386EVO, Pressfit 30 and BBright bottom brackets. This ensures that the bearings are positioned as far outwards as possible and the crank axle is supported in the best possible way. 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 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.

30 mm crank axles:

Cranksets with a continuous 30 mm axle are available from various manufacturers, e.g. the Cane Creek eeWings, FSA BB386EVO, e*thriteen, Race Face Chinch 30, Sram EVO 86 and Rotor 30. These crank axles are longer than those of BB30 cranks and can therefore also be fitted to frames with bottom bracket shells 79–92 mm wide.

BBright bottom bracket shells:

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