Bring your downhill drivetrain back to crisp, race-ready shifting with this genuine SRAM service part. This is the replacement short cage assembly for the 2012-era X0 DH 10-speed rear derailleur, finished in red so it matches your original cage instead of forcing a whole new derailleur.

• Genuine SRAM replacement cage assembly, not a complete derailleur
• Sized for the X0 DH short-cage layout used on downhill drivetrains
• 10-speed specific, built for SRAM Exact Actuation shifting
• Red finish to match the original X0 DH cage
• Restores shift quality without replacing the whole rear mech

What it is

The cage assembly is the lower, swinging part of the rear derailleur that carries the pulley (jockey) wheels and routes the chain. After a hard season of downhill riding, rock strikes and crashes most often damage the cage rather than the derailleur body. Swapping just the cage assembly is a cost-effective way to revive an otherwise healthy X0 DH derailleur.

Short cage for downhill

The short cage is purpose-built for the narrow-range cassettes used on downhill bikes. A shorter cage keeps the derailleur tucked up and away from trail hazards and helps hold chain tension over rough terrain, where chain slap and dropped chains are a constant threat.

Fit and compatibility

This is a 10-speed component designed for SRAM Exact Actuation (1:1) drivetrains. It is intended specifically as the short cage service part for the 2012 SRAM X0 DH 10-speed rear derailleur. Confirm your existing derailleur is the X0 DH short-cage 10-speed model before fitting, and have the swap carried out by a qualified mechanic so cage tension and pulley alignment are set correctly.
