• Enhanced Heat Dissipation: This bicycle brake cooling disc features a floating ice rotor with polygonal airflow design and double-row hollow heat sink that rapidly conducts heat away from the braking surface, preventing brake fade during long descents or intense riding sessions on mountain or road bikes.
• Stable Dual-Piston Braking: The hydraulic disc brake system includes a three-finger brake handle and dual-piston caliper design for consistent, reliable stopping power. This setup delivers smooth modulation and strong braking performance even in wet or dusty trail conditions.
• Universal Bike Compatibility: Designed for wide applicability, this brake cooling disc fits most standard bicycles with 22.2mm handlebars and supports common rotor sizes (Front 180mm, Rear 160mm). Ideal for mountain bikers, road cyclists, and commuters seeking upgraded braking control and safety.
• Premium Aluminum Alloy Build: Made from lightweight yet durable aluminum alloy, the floating ice rotor balances strength and weight efficiency. The material resists warping under high heat and ensures long-term performance without adding unnecessary bulk to your bike’s braking system.
• Optimized Friction & Easy Installation: The brake lever features a frosted surface with concave holes to increase grip and reduce slippage from sweat, while the package includes 2 disc brakes, 2 rotors, 16 screws, and 1 conversion block for straightforward front and rear setup on compatible frames.
