Комплект для балансировки колёс Silca SpeedBalance

SpeedBalance is the world's first Aerodynamic Wheel Magnet AND tunable balancing system for high performance cycling.  SpeedBalance replaces your spoke magnet with a rim mounted aerodynamic magnet that can save up to 1 watt at 30mph.  4 Tungsten slugs inside the SpeedBalance weigh 2.5 grams each allow for custom wheel balancing up to 10 grams to offset valve stem weight and create perfectly balanced wheels to eliminate high speed vibrations and improve handling.
