Hayes Dominion A2 Brake

Expanding on our award-winning Dominion A4, our newest brake, the Dominion A2, targets cross country and trail riders. The Dominion A2 features a two-piston caliper and includes all the performance from the Dominion A4, utilizing a compact design. With the SFL option, the Dominion is the ideal brake for any rider with smaller hands. The Hayes product development team designed a brake system specifically for a smaller ergonomic profile.

The Dominion SFL maintains all the power and feel of our proven Dominion A4, accomplished through a specifically designed smaller and narrower brake lever. The Dominion SFL can be used with either our Dominion A2 two-piston caliper or our Dominion A4 four-piston caliper. With optional lever sizes and two caliper choices, the Dominion from Hayes Disc Brake now offers a brake that's ideal for your application.

The Dominion A2 features the proprietary QuickBite system for fast and consistent burnish, coupled with our D-Series rotor to manage heat with less braking noise. It is available in SFL (Small Finger Lever), which is ergonomically tailored for smaller hands.

Please note that this price is for one brake. If you are looking for a set for the front and rear, you need to order two brakes. The Dominion is "flip-lever," so it can be used for both sides. Rotors and brackets are not included.
