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!
