The new X0 trail brake from Avid is designed to eat up rough terrain, according to Sram's press release. With a 4-piston brake calliper, in which two pairs of pistons each have a different diameter, and an elaborately mounted brake lever, the Americans promise high braking power and good modulation at the same time.

The XO Trail brake weighs 340 grams (in the front brake version with a direct mount 160 mm brake rotor), and the tool-free adjustment of the lever width and brake pad contact point are also on board. To eliminate the need for one or even two clamps on the handlebars, the brake can be fixed to the handlebars together with the shift lever and the remote of the dropper post using the Matchmaker feature.

Avid claims that the brake is suitable for far more than just all-mountain use; the stopper is even correctly positioned on long-stroke enduro mountain bikes. According to the manufacturer, initial availability is expected in July 2012. The color versions black anodized and polished silver will be available.

Facelift for the XO brake
The new XO brake is prepared for less vicious terrain, but at 315 grams (in the front brake version with direct mount and 160mm brake rotor), the stopper is a little lighter than its trail counterpart. The brake has to make do with two pistons on the caliper, so unlike the Trail version, there is nothing more than a facelift visible on this brake. In terms of application, Sram sees this decelerator as being correctly positioned in the cross-country to all-mountain range. In terms of color, the new XO brake comes in silver, red or black.

New: 170 mm brake rotor
New from Avid is a 170 millimeter brake rotor, which is intended to represent a compromise between low weight and high braking power. According to the manufacturer, the new brakes are expected to be available for the first time in July 2012. The new stoppers retain the Matchmaker feature for a tidy steering center.
