Low rolling resistance has a lot of advantages to list - riders can reach top speed more quickly, maintain that speed longer, and keep their legs fresher for the finishing sprint, among others. The tubeless construction of the Formula PRO series cuts rolling resistance by 20% compared to traditional tubed tires. Tubeless tires also tolerate a wider range of pressures, which can increase comfort and reduce exertion.
Comparison of time to pressure loss after puncture
Tubeless tires integrate the air-sealing layer into the tire, and even punctures caused by foreign objects when riding do not result in the kind of hole propagation that occurs with conventional tubed tires, so that pressure loss is comparatively gradual in most cases. When pierced by a plunger with a diameter of 1.7 mm, the time required for internal pressure loss was roughly ten times as long. For this reason, small punctures often stay small, greatly reducing the chances of wrecks.
Because the butyl rubber air-seal is integrated with the tire, the air volume contained by it and the rim on Formula PRO tubeless tires have almost no natural leakage compared to conventional tubed tires. This eliminates the need to top off tires every day, so you can hop on your bike and ride without worrying about maintenance. And when mounting tubeless tires, there's obviously no inner tube to get caught between the bead and rim, eliminating one of minor annoyances, the burst tube.
To bring the advantages of a latex tube to a tubeless tire, IRC developed a new high-elasticity tire liner based on natural rubber which offers lower energy loss, reinforced with silica. Despite being slightly poorer at retaining air than the butyl rubber used for typical liners, air retention is sufficient, especially for tubeless construction.
The Usage Scale is your guide to matching an lRC tire to your preferred terrain and riding style. Read the scale as a range, with the highlighted cell indicating optimum use. A highlighted cell falling in the middle of the range indicates that the tire is equally suited for the condition at each end of the range. Keep in mind that this is only a guide as lRC tires work well in a variety of conditions.
