SpeedBalance is the world's first Aerodynamic Wheel Magnet AND tunable balancing system. Built as part of the SILCA Tubeless Collection, it was designed for performance-oriented cyclists with carbon wheels. SpeedBalance is a rim mounted aerodynamic magnet that can save up to 1 watt at 30mph. Four tungsten slugs inside the SpeedBalance allow for custom wheel balancing to offset valve stem weight and create a perfectly balanced wheel. Perfectly balanced wheels improve handling, comfort, and confidence -- particularly on high-speed descents.
