Since its first introduction, Tubolight proved to be the winningest tire insert and the only one winning in all disciplines.
We tested many different solutions, looking for the best combination between flat protection, speed, shock absorbtion, stability and weight.
This is the reason why each version has its own shape and compound.
We all know, the two main reasons why tire inserts exist are to the protect from pinch flats and improve ride quality. With the new Tubolight, a new standard is reached.
Studying how pinch flats occur and how tire inserts interact with the tire and the rim, we 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 an harder compound, rim hits are drastically reduced.
The super tight fitting is retained, because that’s an incredible bonus for added lateral stability and avoid tire burp
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.
Tubolight is the winningest tire insert in world cup, and the only one winning in both downhill and cross-country.
