Ison Distribution now distributing Tubolight tyre inserts

Ison Distribution is now distributing Tubolight tyre inserts.

Designed in Italy, Tubolight has achieved success in multiple disciplines, being ridden and tested at enduro, downhill and XC races around the world, most recently winning the Downhill World cup in Fort William with team Commencal/Muc-off rider Amauray Pierron.

Tubolight tested many different solutions, looking for the best combination between flat protection, speed, shock absorption, stability and weight, and this is the reason why each version has its own shape and compound.

“We all know the two main reasons why tyre inserts exist are to protect from pinch flats and improve ride quality,” said a statement. “With the new Tubolight EVO, a new standard is reached. Studying how pinch flats occur and how tyre inserts interact with the tyre and the rim, Tubolight moved material right where it needs to be, over and outside of the rim bead.”

The portion over the rim bead is increased by 30% to 60% depending on rim width, and together with a harder compound, rim hits are drastically reduced. The super tight-fitting is retained.

The air channel between the insert and rim acts like a valve. During a shock, part of the air molecules inside the tyre 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. That means rolling resistance and tyre rebound are reduced.
