CeramicSpeed Shimano XT/XTR 12-Speed NW Derailleur Pulleys

The CeramicSpeed Pulley Wheels for Shimano XT/XTR offers a unique symmetrical 14-tooth narrow-wide design that provides exceptional shift performance. The narrow-wide design delivers precise engagement of the chain, both on and off the pulley wheels. The increased pulley size, compared to stock, reduces chain friction. The pulleys have a lightweight machined alloy body for durability and long life, and are developed, designed and handbuilt in Denmark.

Choose between two options: Machined aluminum pulleys with CeramicSpeed Balls in stainless steel-races or with coated hardened-steel races.
