Introducing the first brake good enough to take the X0 name. Weighing in at only 333g, the full-featured SRAM X0 hydraulic brake features a slim, bar-hugging design that packs all the power and control you have come to expect from the Avid Elixir line of brakes. All-new forged aluminum calipers and lever bodies deliver robust power at a fraction of the weight, and adjustable reach and detented tool-free Contact Point Adjustment makes it easy to dial in perfect performance.
