  • Pulley Wheels for Shimano, 11s NW

    The 12-tooth narrow-wide design on these CeramicSpeed pulleys decreases chain articulation and ensures a crisp chain engagement on to and off of each pulley.

    The symetrical 12-tooth narrow-wide design allows the chain to move smoothly on and off the pulleys without additional friction.

    CeramicSpeed Pulley Wheels for Shimano 11s, 12-tooth is developed, designed and handbuilt in Denmark and comes with seperate dust covers to fit 9100, R8000, RX, GRX, XT and XTR series derailleurs.

    • The Coated Advantage

      Lifetime Warranty Program
      CeramicSpeed’s coated products offer the ultimate gains in performance and longevity. Our unique coating features several attributes that improve the longevity of CeramicSpeed Bearings. The increased hardness of the races, combined with the smoothness of theCeramicSpeed Balls results in virtually no wear on the bearing.

      The coating is a metallic layer, which is 75% harder than the hardened steel races. The coating is applied in a very thin and even layer of 3 microns (0,003 mm) on the entire surface of the bearing race. Both the inside and the outside are treated to achieve optimal results.

      Within our comprehensive R&D program, the special coating has been developed in cooperation with a European coating specialist. Applied to the bearing’s steel races, through an advanced process that ensures an even, smooth and homogeneous surface, the coating formula improves even further the high quality of CeramicSpeed Bearings.

      Thanks to the coating’s high resistance to corrosion – even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible. We recommend choosing CeramicSpeed Coated Bearings for unmatched longevity and incredibly low friction.
