Welcome The New Era of Silent Pulleys
Does it bother you when you ride in really quiet scenery, but you can still hear your bike's drivetrain? This familiar clunking noise has been accompanying us on every ride for decades. But it's time for change!
Full Ceramic Bearings
These absoluteBlack Carbon HOLLOWcage bearings are full ceramic which in technical terminology means you have a bearing with inner and outer race as well as balls, made of ceramic material. The seals and the cage, however, are made of polymer. Other common types of bearings are steel bearings and hybrid bearings. The latter is often mistakenly called a "ceramic" bearing but only the balls are ceramic. The races are still made of steel. Hence there is a term "full ceramic" indicating that not only the balls are made of ceramic but both races too. Their bearing races are made out of 100% Zirconia Oxide ceramic and balls are made of Silicon Nitride ceramic and the cage and seals are made of low friction polymer.
