Description

This disc brake features a "Small Finger Lever" brake lever with tool-free reach adjust, which means that you can fine-tune it to perfectly match your hand size, riding preferences as well as the terrain conditions. Hayes has also equipped this model with a two-piston caliper that provides fast and reliable braking as you blast across the rock yard; lawn, tree roots and debris at speed.

Expanding on the 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, utilizing a compact, two-piston caliper. With this 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 the proven Dominion A4, and accomplishes this using a specifically designed smaller and narrower brake lever. 

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

This option is the SFL Small Finger Lever version - ergonomically tailored for the smaller hand.
