RCB E2 SERIES BRAKING SYSTEM
RCB S1 SERIES BRAKING SYSTEM
RCB S1 Replacement Lever (Right Hand Side) is a premium, high-strength control component engineered specifically as a direct-fit replacement for the flagship RCB S1 Series Radial Master Brake Pump.
When a bike tips over, the brake lever often bears the brunt of the impact. This right-hand replacement blade restores the exact ergonomics, throw distance, and fluid leverage of your original S1 radial pump setup, bringing your front braking response back to peak tracking performance.
Key Features
-
Precision CNC-Machined Billet Aluminum: Fully sculpted from high-tensile billet aluminum alloy. This structural choice provides exceptional rigidity, completely eliminating lever flex under aggressive, high-pressure emergency stopping conditions.
-
True Radial Pivot Ergonomics: Specifically contoured to match the perpendicular stroke alignment of the RCB S1 Radial 14mm and 17mm master cylinders. This ensures an instantaneous, crisp mechanical feel and direct hydraulic feedback.
-
Integrated Multi-Position Dial Adjuster: Features a premium click-adjust dial mechanism on the face of the lever body. This allows you to fine-tune the initial distance between the lever blade and your handlebar grip, catering perfectly to varying hand sizes and glove thicknesses.
-
Aerodynamic Aerodynamic Vent Line: The outer third of the lever blade features a stylized cutout slot. This vent line prevents high-velocity aerodynamic wind pressure from accidentally acting against the lever and causing brake drag at track speeds.
-
Structural Fail-Safe Breakaway Groove: Engineered with a clean snap line near the outer tip. In the event of a crash, the tip is designed to break away under localized stress, preserving the main body of the lever so you can still hold the front brakes and finish your ride.
