The Faster, Lighter Tyre Insert

Since its first introduction, Tubolight proved to be the winningest tyre insert and the only one triumphant in all disciplines.

We 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.

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.


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 gets trapped and take 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 tire rebound are reduced.
These two features combined give what every rider is looking for: EFFICIENCY.

Downsides? Yes, there are two minor downsides: wether using mousse-specific or standard valves, air release is slightly slower due to the pressure difference between the two portions of the air volume.
At first installation, we suggest not to put sealant from the valve.
