    Race Ready MTB Disc Brake with Small Finger Lever (SFL)

    Expanding on the brand's award-winning Dominion A4. The Dominion A2, targets Cross Country and Trail riders. Dominion A2 features a two-piston caliper. Dominion A2 includes all the performance from the Dominion A4, utilising a compact, two-piston caliper. With the SFL option (this version), 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 the proven Dominion A4, and accomplishes this using a specifically designed smaller and narrower brake lever. Dominion A2 features the proprietary QuickBite system for fast and consistent braking performance and it is compatible Hayes D-Series rotors to manage the heat with less braking noise (rotors are available separately).
