This results in a smooth balance between power and modulation, helping you manage steep descents with confidence.Short-stroke Servo-Wave mechanism with SIL-TEC roller: Reduces lever travel for quicker pad engagement. This allows faster braking response with less effort, which supports aggressive riding styles.Forged one-piece calliper and lever body: Increases rigidity while reducing weight. This enhances braking stability under load, especially in high-speed trail conditions.Second braced bar contact point on the lever: Boosts master cylinder and lever stiffness. This delivers a consistent and direct braking feel, even during repeated hard stops.Free-stroke and reach adjustability: Lets you fine-tune pad engagement and lever position. This ensures a comfortable and tailored fit for different hand sizes and riding preferences.Textured, up-swept 14 mm brake lever with ergonomic pivot: Improves grip and lever control. The natural finger motion helps maintain power with less fatigue over long descents.Low Viscosity Oil system: Keeps fluid performance stable across wide temperature changes.
