The Silca SpeedBalance Kit is an aerodynamic wheel magnet and tunable balancing system designed to maximize wheel efficiency and stability. Unlike standard spoke-mounted magnets, SpeedBalance mounts directly to the rim, improving aerodynamics by up to 0.5 watts at 30 mph and saving up to 1 watt at 50 kph. Inside the SpeedBalance are 2.5 g tungsten slugs that let you fine-tune wheel balance—up to 10 g—to counter valve stem weight. The result: smoother high-speed performance, reduced vibration, and more precise handling. Sleek, smart, and performance-focused. Key Features:• Rim-mounted aerodynamic magnet improves efficiency up to 0.5 W at 30 mph• Saves up to 1 watt at 50 kph• Includes tunable tungsten slugs (2.5 g each)• Balance wheels up to 10 g• Reduces high-speed vibration and improves handling• Premium, low-profile design Ideal For: Riders seeking aerodynamic gains, smoother wheel balance, and better high-speed stability.
