Bottom Bracket Wheels Manufacturing

The outboard bottom brackets from Wheels Manufacturing allow Sram DUB MTB and road cranksets with a 29 mm axle to be fitted into frames with Pressfit30 bottom bracket shells with a 46 mm press-fit depth at 68 and 73 mm widths.

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

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.

Sram DUB crank axles 29 mm:

SRAM has developed its own axle standard for the DUB cranks. The SRAM DUB cranks have an axle diameter of 29 mm and are only compatible with bottom brackets designed for DUB cranks.

Pressfit 30 / 68–73 bottom bracket shells:

The 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 bearing sleeves 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 bearing sleeves.
