Bottom Bracket Wheels Manufacturing
The T47 threaded bottom brackets from Wheels Manufacturing for MTB and road bike cranksets with a 24 mm axle, designed for installation in frames with T47 bottom bracket shells measuring 68–132 mm in width
Wheels Enduro ABEC5 angular contact ball bearings:
The Wheels Enduro ABEC5 angular contact full-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.

Shimano Hollowtech II 24 mm bottom bracket / Road - MTB:
The Shimano Hollowtech II crankset system features a solid 24 mm axle. The road bike cranks have an axle length of 110 mm and the MTB cranks 120 mm. This axle system is also used on the FSA Megaexo cranks and the Race Face X-Type cranks. The respective bottom brackets are compatible with one another. The DH Saint and Zee cranks for 83 and 100 mm installation widths have longer axles and will only fit frames with correspondingly wider bottom bracket shells.
FSA MegaExo 24 mm / Road - MTB:
The FSA MegaExo crankset system features a solid 24 mm axle, in line with the Shimano Hollowtech II system. However, some models are fitted with a 24.7 mm axle. These bottom brackets are not compatible with those models.
Race Face X-Type crank axle 24 mm:
The Race Face X-Type crankset has a 24 mm through-axle, just like the Shimano Hollowtech II cranks. The X-Type MTB cranks for 73 mm and 68 mm bottom bracket shells have an axle length of 120 mm. The cranks for 83 mm bottom bracket shells have an axle length of 136 mm. This axle system is also used on FSA MegaExo cranks. The respective bottom brackets are compatible with one another.
T47 threaded bottom bracket cups
The bottom bracket shells have a width of 68 to 132 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 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.
