The X4 offers the proven SRAM 2-lever trigger shifting performance in a more affordable price point. Featuring our proven ergonomics and award-winning 1:1® Actuation, this trigger shifter sets the standard for entry level performance and value.
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.
