Wheels Manufacturing Threaded MTB Angular Contact Bottom Bracket

This bottom bracket is specifically designed for GXP cranksets with a 22/24mm spindle diameter. It is not compatible with standard 24mm Shimano or 30mm spindle cranks.

This unit fits frames with a standard BSA (English/ISO) threaded bottom bracket shell. It is compatible with shell widths of 68mm or 73mm, and the included spacer kit ensures a precise fit for both.

Angular contact bearings are designed to handle both radial and axial loads simultaneously, which is ideal for the side-loading forces common in mountain biking. This results in smoother rotation under pressure and increased durability compared to standard radial bearings.

Yes, it is fully serviceable. The design allows you to access, clean, and re-grease the bearings, which significantly extends the lifespan of the component compared to sealed, non-serviceable units.

It features high-quality silicone dust seals that provide a robust barrier against water, grit, and mud. While no bottom bracket is completely impervious to the elements, these seals are specifically engineered to keep the bearings protected during demanding trail rides.
