Expanding on our award-winning Dominion A4. Our newest brake, Dominion A2, targets Cross Country and Trail riders. Dominion A2 features a two-piston calliper. Dominion A2 includes all the performance from the Dominion A4, utilizing a compact, two-piston calliper. With the SFL option, the Dominion is the ideal brake option for any rider with smaller hands. Hayes product development team set out to design a brake system specifically designed for a smaller ergonomic profile. 

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

Dominion A2 features the proprietary QuickBite² system for fast and consistent burnish, coupled with our D-Series rotor to manage the heat with less braking noise.

Available in SFL (Small Finger Lever) - ergonomically tailored for the smaller hand.
