Bottom Bracket Wheels Manufacturing

These threaded bottom brackets from Wheels Manufacturing allow MTB and road cranks with 30 mm axles to be fitted into frames with PressFit 30 bottom bracket shells, which have a width of 68–73 mm and a press-fit depth of 46 mm. These bottom brackets are compatible with cranksets featuring a 30 mm axle system, such as Cane Creek eeWings, FSA BB386, Race Face Cinch 30, Rotor 30 and Sram BB386Evo cranksets. These cranksets have longer axles, from 103 mm, than BB30 cranksets. BB30 cranksets cannot be fitted to these bottom brackets. The axle length must be more than 103 mm for 68 mm wide bottom bracket shells and more than 108 mm for 73 mm wide shells.

Unlike other press-fit bottom brackets, the Wheels Threaded Manufacturing cup sets 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.

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 within 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:

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 86, 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.

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.
