Wheels Manufacturing Outboard Bottom Bracket

The bolted outboard bottom brackets from Wheels Manufacturing allow MTB and road cranks with a 24 mm axle to be fitted to frames with road bike BB86 and MTB BB92 bottom bracket shells, which have a width of 86–92 mm and a press-fit depth of 41 mm. Also suitable for Trek frames with PressFit 90 bottom bracket shells

Unlike other press-fit bottom brackets, the Wheels Manufacturing cups 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.

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.

The Shimano Hollowtech II crankset system features a solid 24 mm axle. The road bike cranks have an axle length of 110 mm, whilst the MTB cranks for 73 and 68 mm bottom bracket shells have an axle length of 120 mm. This axle system is also used in FSA Megaexo cranks and Race Face X-type cranks. The respective bottom brackets are compatible with one another.

BB92 bottom bracket shells:

BB92 bottom bracket shells have a width of 89 to 92 mm and a press-fit depth of 41 mm. These bottom brackets are only compatible with MTB cranksets. Not compatible with MTB cranksets for 83 and 100 mm installation widths. These bottom brackets are press-fit.

Pressfit 90 Trek bottom bracket shells:

The Pressfit 90 bottom bracket shells on Trek frames have a width of 90 mm and a press-fit dimension for the bottom bracket of 41 mm. These bottom brackets are press-fitted. With Wheels 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 installation, as the bearings are additionally secured by the bottom bracket cups.
