A quality cassette body can be the key toproviding the ultimate performance from a top quality pair of wheels. The BlackInc Shimano Cassette Body has been engineered to provide low friction and quickengagement in order to make the most out of the aero efficiency of our wheels.It is available with stainless steel bearings or upgradable to CeramicSpeedbearings for a smooth, practically friction-free ride.
We work directly with CeramicSpeed for allour hubs, which is why we offer the Shimano freehub body with ceramic bearingsas an option. CeramicSpeed bearings are based directly on the technologydeveloped as part of NASA’s space program in the 1990s. CeramicSpeed bearingsare produced using top-grade Silicon Nitride ceramic balls which provide aninstant upgrade from steel bearings. We design our hubs according to theextremely high tolerances that CeramicSpeed handmade bearings allow for.
In both configurations, either withstainless steel or CeramicSpeed bearings, Black Inc Shimano Cassette Bodyoffers extensive durability and lightweight efficiency. Fast engagement andequally reliable disengagement when coasting are hallmarks of the Shimanofreehub performance.
