The REVOLOOP.race ultra is the lightest bicycle tube in the REVOLOOP family. Developed by enthusiasts for enthusiasts, this tube makes no compromise. Weighing only 25 grams, it saves about 50% compared to conventional butyl hoses. The specific material coordination of the thermoplastic polyurethane gives this tube its unique latex-like rolling characteristics and minimises rolling resistance. For a few watts of extra freedom!
The valve is made of 'impact and break resistant' thermoplastic and is ahead of its time. Minimum weight combined with maximum performance. A specially designed valve foot prevents damage to the hose due to sharp edges on the valve bore.
