The difference between fast and first.
If you’re going to be the brake component in the most advanced cross-country family ever, you have to be remarkable. XX is the highest performing cross-country brake anywhere because it incorporates all the stopping power and precise control of Elixir. At a mere 288 grams the XX is crazy light thanks to the two-piece forged magnesium caliper and sleek carbon fiber lever blade. And to top it off, the U-Clamp and CleanSweep X rotor take smart, efficient, beautiful product design to the next level. XX truly is the lightest—yet fully featured—hydraulic disc brake in the world today.
