Wheels Enduro ABEC5 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 surface, reducing friction and wear. The balls in these Enduro bearings are manufactured to extremely high precision with a tolerance of just 10/1,000,000, twice as precise as standard industrial bearings. Fitted with double silicone seals, double lip seals and heavy-duty grease, these bearings guarantee excellent durability. Enduro bearings are easy to maintain and are interchangeable.
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 and Rotor 30 models. These crank axles are longer than those of BB30 cranks. A minimum axle length of 104 mm is required with a 68 mm bottom bracket shell width. Not BB30 compatible.
T47 threaded bottom bracket cups
The bottom bracket shells have a width of 68 to 121 mm and a 47x1.0 mm thread, with an outer diameter of 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 scope of delivery.
Wheels MFG offers the T47 bottom brackets in two versions: Inboard T47, with narrower cup shells for the 86.5, 89.5 and 121 mm wide T47 bottom bracket shells, and the Outboard T47 bottom bracket with wider cups for 68, 73 and 100 mm T47 bottom bracket shells.
