Derailleurs & Pulley Systems
Upgrade or repair your drivetrain with rear derailleur parts made for selected road bike groupsets. This collection includes oversized pulley wheel systems, derailleur pulley wheels, replacement hangers and titanium fitting kits.
An oversized pulley wheel system can change the appearance of a drivetrain while using larger wheels to guide the chain. You will also find smaller replacement parts, including bike derailleur hangers, shifter bolts and jockey wheel bolts.
Fit varies between Shimano, SRAM and other drivetrain models. Check the groupset generation, derailleur model and product measurements carefully before ordering. Shop options from Tripeak, S-Parts and other specialist component brands.
