SRAM X0 Medium Cage 10 Speed Mechanical Mountain Rear Derailleur

We're a mission-driven bike shop based in Colorado. Every sale helps refurbish and donate bikes to those in need through Bicycles for Humanity Colorado. Each item has been professionally inspected, thoroughly cleaned, carefully refurbished, and is ready for immediate use.

The SRAM X0 rear derailleur represents SRAM's pinnacle of 10-speed mountain bike mechanical shifting performance, sitting just below the XX1 flagship in the lineup and offering an exceptional blend of precision and durability. This unit features SRAM's Exact Actuation system for crisp, positive gear changes, a robust aluminum parallelogram body with carbon fiber cage components, and the X0's signature sealed bearing jockey wheels for smooth, low-friction chain guidance. The derailleur shows light to moderate signs of use with some scuffs and minor paint chips visible on the cage and body, but all pivot points and springs function freely with no bent hanger tab or structural damage. The derailleur is well-suited to aggressive trail and XC riding where reliable 10-speed shifting and low weight are priorities, and pairs directly with SRAM 10-speed trigger shifters and any standard hanger-mount frame.

Every item from Traveling Ground is fully refurbished, professionally inspected, and ships next business day.
