Wheels Manufacturing Outboard Bottom Bracket

The bolted 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 BB86, BB92 and Trek Pressfit 90 bottom bracket shells, which have a width of 86–92 mm and a press-fit depth of 41 mm.

BB86 bottom bracket shells:

BB86 bottom bracket shells have a width of 86 mm and a press-fit depth of 41 mm. These bottom brackets are only compatible with road bike cranksets. These bottom brackets are press-fit.

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 cranks. Not compatible with MTB cranks for 83 and 100 mm installation widths. These bottom brackets are press-fitted.

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.

Sram GXP crank axle:

The Sram GXP crankset system with 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 bottom bracket cups are bolted together. This has the major advantage that the bottom bracket cups, and therefore the bearings, sit very firmly and absolutely parallel within the frame. This reliably prevents the annoying and irritating creaking and grinding of the bearings in the frame. Even frames with slightly worn-out bottom bracket shells can often still be used with this system. This ensures a long service life for both the bottom bracket and the frame. 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.
