The REVOLOOP.mtb Ultra is the perfect high-performance tube for the steepest of climbs. At only 45 grams at 29 inches, it saves about 100 grams per wheel making starting and climbing less strenuous.
The valve is made of particularly impact and break-resistant thermoplastic and is at the forefront of bicycle tube technology. Minimum weight coupled with maximum performance. A specially designed valve foot prevents damage to the hose due to sharp edges on the valve bore. The tough plastic minimizes valve breakage during the toughest trails with low air pressure.
