Bottom Bracket Wheels Manufacturing

These threaded bottom brackets from Wheels Manufacturing allow MTB and road cranksets with 30 mm axles to be fitted into frames with Pressfit 30, Specialized Carbon OSBB and BBRight bottom bracket shells with a width of 61–79 mm and a press-fit depth of 46 mm.

Unlike other press-fit bottom brackets, the Wheels Manufacturing threaded bottom bracket cups are screwed 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.

30 mm crank axles:

Cranks with a continuous 30 mm axle are offered by various manufacturers, e.g. the Cane Creek eeWings, FSA BB386EVO, e*thriteen, Race Face Cinch 30, Sram EVO 386, Rotor 30 and White Industries models. 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.

BB30 crank axles 30 mm:

BB30 cranks with a solid 30 mm axle are available from various manufacturers. These crank axles are shorter than the axles of EVO30 cranks and can therefore also be fitted to frames with bottom bracket shells that are only 61–79 mm wide.

Wheels Outboard bottom bracket compatibility:

Compatible with BB30 MTB and road bike cranksets, as well as DZero power meters. Shimano Hollowtech II and Sram GXP cranksets can also be fitted using the adapters (item nos. BBUNIV-SHIM and BBUNIV-SRAM). The Wheels WRENCH-BB48-44 tool is required for installation. The standard Hollowtech tool does not fit

Wheels Enduro Angular Contact Ball Bearings:

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

Pressfit 30 / 68–73 bottom bracket shells:

Pressfit 30 bottom bracket shells have a width of 73 to 68 mm and a press-fit dimension for the bottom bracket of 46 mm. These bottom brackets are pressed in. 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 assembly method, as the bearings are additionally secured by the bottom bracket cups.

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 assembly method, as the bearings are perfectly secured within the frame by the bottom bracket cups.

Specialized Carbon OSBB bottom bracket shell

The Specialized Carbon OSBB bottom bracket shells have a width of 61 mm and a press-fit dimension for the bottom bracket of 46 mm. Additionally, a spacer set comprising 2 x 2.5 mm and 1 x 1 mm spacers is required, item no. SP0001. These bottom brackets are press-fit. 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 assembly, as the bearings are additionally secured by the bottom bracket cups.
