Bottom Bracket Wheels Manufacturing

The T47 threaded bottom brackets from Wheels Manufacturing allow Sram DUB cranksets with a 29 mm axle to be fitted into frames with T47 bottom bracket shells measuring 68 mm, 73 mm or 100 mm in width. The Enduro bearings can be replaced and are easy to maintain.

The T47 bottom brackets are available from Wheels 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.

T47 threaded bottom bracket shell

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