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 with 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 cranksets. Not compatible with MTB cranksets 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 bearing cups are screwed together. This has the major advantage that the bottom bracket shell sits very firmly and absolutely parallel within the frame. This means you can continue to use or salvage frames with slightly worn-out bottom bracket shells. 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 Angular Contact Ball Bearings:

The Wheels Enduro ABEC5 angular contact ball bearings are specially designed for use in hubs and bottom brackets. Whilst 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.
