Evo Features Since its first introduction, Tubolight proved to be the winningest tyre insert and the only one winning in all disciplines.Tubolight tested many different solutions, looking for the best combination between flat protection, speed, shock absorption, stability and weight.
Air Channel The air channel between insert and rim acts like a valve. During a shock, part of air molecules inside the tire move from the outer portion of the insert into the channel, causing a difference in pressure. As the insert is very tight on the rim, those molecules get trapped and take a fraction of time longer to re-establish even pressure between the outer and inner portion.
