Rigorous R&D Design: To ensure that the small air chamber can release a large energy during cycling, RideNow has made many efforts and attempts from material formulation to production technology, and finally got the Race Formula air chamber you see. HIGH QUALITY AIR VALVE - RideNow uses special reinforcement materials to manufacture TPU air chamber valves, which are structurally stable, sturdy and durable. We will provide warranty for all quality problems related to valve damage. Unimaginable lightness: Taking the inner tube for road bikes as an example, Race Formula offers three versions: 36 g, 24 g and 19 g. The lighter version, at 19 grams, is even lighter than the self-refilling liquid that is injected into vacuum tires.
