Avid split its X0 Disc Brakes into two distinct versions. One aimed for aggressive trail riders, aptly named 'Trail' -- for those that prefer power and adjustments over weight. And, standard X0 which favors low-weight over complexity.
While the Trail model differs greatly from previous versions of X0, this one builds on the existing two-piston, two-piece caliper from previous iterations -- with an updated lever assembly. This isn't the old give it a new finish and mark-it-up approach.
The X0 brake continues to utilize Avid's Taperbore technology to offer progressive modulation. But, in the spirit of weight reduction, it forgoes the pad contact adjustment. You can still adjust reach to place the carbon lever in the most ergonomic position. Unlike the Trail lever, though, this model rotates around a hollow pivot and bushing instead of a bearing and solid pivot assembly.
These two features alone drop the system's weight to just over 300 grams, without sacrificing performance. At the caliper end of things Avid continues to employ its proven two-piston units. They're constructed from forged aluminum for stiffness and cooling efficiency, and it uses a banjo fitting for the braided polyester hose.
This allows clean routing on the majority of frame designs with standard post mounts. Speaking of clean aesthetics, the X0 brakes are fully compatible with Matchmaker to offer ergonomic and space saving mounting for compatible remotes and shifters.
The Avid X0 Disc Brake comes with either a polished aluminum or black finish. Front and rear brakes are sold separately, and rotor sizes are 160, 180, or 200mm.
