SRAM X7 Rear Derailleur - 9 Speed

1:1 Actuation™ 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. Easiest to set up. Easiest to adjust. And, not coincidentally, the top choice of the top MTB riders. Got it? Good.

Here's the dirt on middlemen: they suck. That's why Direct Route Technology™ doesn't have one. Instead, the cable routes directly to the actuation mechanism. Result? Less friction. Less effort. More oomph. Plus it's impervious to cable housing damage. Nice.
