SRAM just announced all-new XX and XX World Cup (XXWC) hydraulic disc brakes. Borrowing heavily from the recent Elixir 7 & 9 redesign, the new magnesium lever body is similar between the two brakesets and gets the revised bleed port location and air trap to improve bleed performance. From there, they did what they always do for their top-level spec and shaved grams.
The new XX levers appear to have a lower profile Pad Contact Adjust bezel and tooled reach adjust rather than the Elixir’s knob. The XXWC lever does away with the Pad Contact Adjust to save weight, and the master cylinder body is much sleeker and tapered toward the lever pivot (pics below). If you’re not using the MatchMaker mounts, the XX clamp is a little more chiseled, too.
The real newness comes in the calipers. Both get all new castings, and both do away with their CPS (Caliper Positioning System – the small cupped washers that make lining up the calipers easy that have come with Avid brakes forever). The alloy XX calipers are essentially the same as the new Elixirs, but the mounting surface is extended slightly to make up for the gap otherwise filled by the CPS washers. Claimed weight is 289g per wheel.
The XXWC, however, gets a sleeker magnesium caliper with larger pistons for a system weight (claimed, front 160mm) of 270g per wheel. That’s 88g lighter than the new Elixir 9 and 18g lighter than the current XX brakeset…and puts it just under the Ashima’s we just reviewed.
More pics and the official PR after the break…
