About Tubolight Evo Road Tyre Insert - Pair
The Faster, Lighter Tyre Insert. 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 because that’s an incredible bonus for added lateral stability and avoiding tyre burp.

The air channel between the insert and rim acts like a valve and during a shock, some of the air inside the tyre moves from the outer portion of the insert into the channel, causing a difference in pressure. As the insert is very tight on the rim, this air gets trapped and takes a fraction of time longer to re-establish even pressure between the outer and inner portion.

That means, in the real world, rolling resistance and tyre rebound are reduced.

These two features combined give what every rider is looking for: Efficiency.

Designed for large bag tyres & low pressures providing security for riders at the lowest possible weight.

About Tubolight
The Faster, Lighter Tyre Insert. Since its first introduction, Tubolight proved to be the winning tyre insert and the only one triumphant in all disciplines. Tubolight tested many different solutions, looking for the best combination between flat protection, speed, shock absorption, stability, and weight. Hence why each version has its own shape and compound. The two main reasons why tyre inserts exist are to protect from pinch flats and to improve ride quality, but with Tubolight, a whole new standard is attained.
