A quality freehub body can be the key to providing the ultimate performance from a top quality pair of wheels. The Black Inc X Shimano Micro Spline Freehub Body has been engineered to provide low friction and a quick 30-tooth engagement in order to make the most out of the aero efficiency of our wheels. It comes standard with CeramicSpeed bearings for a smooth, practically friction-free ride.
CeramicSpeed bearings are based directly on the technology developed as part of NASA’s space program in the 1990s. CeramicSpeed bearings are produced using top-grade Silicon Nitride ceramic balls which provide an instant upgrade from steel bearings. We design all of our hubs according to the extremely high tolerances that CeramicSpeed handmade bearings allow for.
