Tubolight EVO HD 48 mm Anti-Puncture Mousse

Automatic translation Original description available here

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.

Even though the new shape is shallower, 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 U shape on the top gives room for more air tuning, other than saving weight and thus allowing for an higher density compound.

The super tight fitting is retained, because that’s an incredible bonus for added lateral stability and avoid tire 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.
