Overview

The limited-edition Dominion T2 distills the Dominion family legendary power and sensitivity into the lightest chassis Hayes has ever made. A Reynolds-designed and in-house produced carbon-fiber lever saves significant weight while improving feel in cold conditions, backed by titanium hardware, a composite reservoir cover, and pads with aluminum backing plates. The result is a 2-piston brake that weighs just 254g — 50g lighter per brake than the Dominion A2 — without giving an inch on the modulation and reliability that made the Dominion a benchmark.
