Technologies:

Low Input - High Fidelity (LoFi): Low effort system with predictable, progressive ramp-up and a crisp bite point.
Reduced Friction: A featherlight lever feel is achieved through a combination of an added glide ring on the piston and sealed ball bearings at the lever blade pivot.
SRL: The Stable Rate Link delivers a consistent lever ratio regardless of reach.
Precise Engagement: Each Dominion is factory set to have the lowest dead stroke possible and a crisp bite point.
Built to Last: Metal pistons are used to ensure that no matter the terrain or temperature your brake will continue to perform as it did on the first ride.
Adjustable Reach: Adjust your lever reach with ease while on the trail thanks to an intuitive adjustment knob design.
Modal Resonance Cancellation (MRC): FEA-optimised modal shapes of D-Series rotors are intentionally designed to oppose those of Semi-Met T106 and Sintered T100 pads, canceling out noise and vibration. Rotors available separately.
Crosshair Alignment System: Patented alignment screws allow for quick and accurate setup.
King Pin: Pad retention bolt adds strength.
