Italian-threaded bottom bracket shells are often found on Italian-brand road bikes. Campagnolo?s Ultra-Torque crank mated to an Italian frame keeps the drivetrain in the family. The shell measures 70mm wide and has a 35mm inner diameter.
CeramicSpeed bearings are pressed onto the spindle and then installed into the cups. Those bearings comprise either Standard or Coated Bearings. Super round, super smooth CeramicSpeed balls rotate in hardened-steel races in both. The Coated version has a metallic coating laid onto the races, making them even harder and smoother, resulting in longer life and lower drag.
