Specifically designed for all-around trail riding performance, the X0 Trail gives you more control and lightens your load.
The robust 4-piston dual-diameter caliper produces more power than any other brake in its class—all in a smooth, svelte package that weighs just 340 grams. Big power without the bulk, the best of both worlds.
