XX World Cup Hydraulic Disc brake

Information from: http://www.sram.com/avid/products/xx-world-cup-hydraulic-disc-brake.

If you’re going to be the brake component in the most advanced cross-country group ever, you have to be remarkable. Meet XX and its new shockingly light brother, XX World Cup. Both incorporate two-piece forged magnesium calipers, carbon fiber lever blades, MatchMaker X compatibility, sexy CleanSweep X rotors and, of course, the stopping power and precise control of TaperBore technology. And if you’re on the ride where every gram counts, the XX World Cup drops an additional 9 grams by dropping Contact Point Adjustment. Either XX takes any true XC machine to the next level.
