Hayes Dominion A2 SRL Disc Brake and Lever
Hayes Dominion A2 SRL Disc Brake and Lever Item # 2139021

Description
The Dominion A2 is an evolution of the award-winning Dominion A4, designed for cross-country and trail riders. Equipped with a compact two-piston caliper, it delivers the same high-level braking performance as the Dominion A4. With the optional Short Reach Lever, it is also an ideal choice for riders with smaller hands or those who prefer a shorter grip distance.
The Dominion SRL retains the braking power and feel of the Dominion A4 with a specially designed smaller and narrower brake lever. It can be paired with either the Dominion A2 two-piston caliper or the Dominion A4 four-piston caliper. With multiple lever sizes and caliper configurations, the Dominion lineup provides a disc brake solution suited to a wide range of riders and riding styles. The Dominion A2 also incorporates the in-house QuickBite system, which quickly and evenly burnishes brake disc surfaces. When paired with the D-Series rotor, it provides optimal thermal management and reduced brake noise.
