Tubolight Blue Tubolight Evo HD 27.5 MTB Insert 2.35-2.8 tubeless insert

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 an 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.
