Ceramic Pulley Derailleur Cage Upgrade for Derailleur System

$22.92

Upgrade your drivetrain with a ceramic pulley derailleur cage built for riders who want smoother gear changes and a wider gear range. This practical bike part replaces the standard derailleur cage and helps a compatible derailleur system rear mech handle more demanding 1x drivetrains with greater confidence. The cage guides the upper pulley into a more efficient position, supporting cleaner gear changes across the cassette and more controlled performance when climbing or accelerating. Its oversized pulley cage design adds a larger lower pulley to reduce friction and improve drivetrain efficiency, while also helping with chain wrap. Built from 7075-series aluminum with hybrid ceramic bearings, it delivers a rigid, lightweight construction at just 62 g. Compatible with derailleur system 11- or 12-speed setups as an expanded-range upgrade for compatible derailleurs. Available in multiple color options.
