When Avid began developing XX, they were looking to create the lightest, most precise and technically advanced components possible, and boy have they delivered! The XX Hydraulic Disc Brake offers superb modulation and heaps of power in a feathery light package. Every detail of this beauty, from the carbon lever to the forged magnesium caliper and titanium bolts, has been intricately designed to enhance control. For even more control, Avid's Deep Stroke Modulation, Power Reserve geometry and adjustable lever reach means you can dial in the XX to work perfectly with your hand. What's more, it comes complete with Avid's HSX rotor, mounting bracket and organic pads for powerful braking, easy installation and smooth modulation.
