Bottom Bracket Wheels Manufacturing

The classic BSA bottom brackets from Wheels Manufacturing allow road bike cranksets with a 24 mm axle to be fitted to frames with 68 mm wide BSA bottom bracket shells.

Compatible with Shimano Hollowtech II, FSA MegaExo, and road bike cranksets with a solid 24 mm axle

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.

BSA threaded bottom bracket shells:

The BSA bottom bracket shells have a width of 68–73 mm and a thread of 1.370 × 24 TPI, with an outer diameter of 33.6–33.9 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 shims included in the delivery.

Shimano Hollowtech II 24 mm road crankset axle:

The Shimano Hollowtech II crankset system has a solid 24 mm axle. The road bike cranksets have a 110 mm long crankset axle.

FSA MegaExo 24 mm / Road:

The FSA MegaExo crankset system has a solid 24 mm axle, similar to the Shimano Hollowtech II system. However, some models feature a 24.7 mm axle. These bottom brackets are not compatible with those models.
