Trail: Meet Your Match In one corner sits the trail ahead: rugged and unrelenting, luring you to go faster one moment, then throwing a tire-catching rootweb in your path the next. Chomping at the bit in the other corner is Avid X0. The newest member of the X0 family, this brake weighs in at a lean 333 grams, complete with forged aluminum lever body and caliper, tool-free contact point adjustment, and the legacy of precision and quality necessary to carry the X0 name. Packing an intuitive design and unmatched feel, X0 gives you the power to lean harder, push further and hit the trail with a one-two punch of performance and control. View Entire X0 Series
