Green KCNC 11T Jockey Wheels - Shimano - 9/10speed - Fit: XTR, Dura Ace, Saint & Sram XO etc

 Two Green anodised 11t jockey (pulley) wheels to fit Shimano nine or ten speed  (Xtr, Xt, DuraAce, Ultegra etc) & Sram XO derailleurs.

Standard wheels often wear out before the derailleur does reducing shifting quality - replace them and revive your derailleur.

These wheels help to improve drivetrain performance in the following ways:

• Ventilated design drives out mud and debris - a must in the UK or offroad.
• Aluminium construction is more durable than standard plastic wheels.

Each wheel weighs 9g on our scales.
