Wheels Manufacturing Bottom Bracket

The T47 threaded bottom brackets from Wheels Manufacturing allow Sram DUB cranks with a 29 mm axle to be fitted into frames with T47 bottom bracket shells ranging from 68 mm to 132 mm in width.

Wheels offers the T47 bottom brackets in two versions: the Inboard T47, with narrower bearing cups for T47 bottom bracket shells 68 to 132 mm wide, and the Outboard T47 bottom bracket with wider bearing cups for 68, 73 and 100 mm T47 bottom bracket shells.

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. Equipped with double silicone seals, double lip seals and heavy-duty grease, these bearings guarantee excellent durability. The Enduro bearings are replaceable and easy to maintain.

T47 threaded bottom bracket shell

The bottom bracket shells have a width of 121 mm and a 47x1.0 mm thread (outer diameter 47 mm), into which the bearing cups are screwed. Both bearing cups are screwed in the direction of travel. Adjustment to the different shell widths is achieved using the washers included in the delivery.
