Why We Like The Hayes Dominion A2 SRL Disc Brake

Upgrading our XC or trail bike with a quality set of brakes like the Hayes Dominion A2 SRL Disc Brake takes our riding to the next level. These powerful 2-piston brakes feature a precise and quick bite point and intuitive features like the tool-free reach adjustment and a flip-flop lever orientation. Installation is kept easy thanks to the dual-port bleed system to ensure proper performance, and the crosshair caliper alignment to help get our caliper centered. This set includes the Dominion A2 caliper, lever, hose, two sets of pads, and mounting hardware.

Must-Have Brakes

Familiarity:
I've used it several times

The Hayes Dominion A2 SRL Disc Brakes are incredible. The 2-piston power is smooth and controlled, giving me confidence on steep descents. The short-reach lever feels natural and reduces hand fatigue, and the tool-free reach adjustment makes it easy to customize. Installation was a breeze with the dual-port bleed system and crosshair alignment. Everything you need comes in the box, too. These brakes are reliable, powerful, and a total game-changer for any XC or trail bike. Highly recommend!
