Sram X5 Rear Derailleur 9 Speed

The SRAM X5 9 Speed Rear Mech features 1:1 Actuation, which is superior by design. Every unit of cable you pull moves the derailleur the same amount.
Actuation stays precise and fluid slogging through mud, bouncing off rocks, rutting through roots - wherever you find yourself, whatever conditions you're in. It's dependable. Tolerant. Easier to set up. Easier to adjust. And, not coincidentally, the top choice of the top MTB riders. Got it* Good.
