EVO FEATURES
Since its first introduction, Tubolight proved to be a winner in all disciplines.
Tubolight's mission: We tested many different options in search of the best combination of even protection, speed, shock absorption, stability, and weight. That's why each version has its own shape and combination. We all know why inserts are designed: to protect the tire from damage and to enhance ride quality.

The new Tubolight sets a new standard.

While researching tire deflation and how inserts work with the tire and rim, we moved material to the right place, on and outside the rim edge. The portion over the rim edge increases 30–60% depending on rim width, and together with a harder compound, rim impacts are significantly reduced. A very tight fit is maintained as it provides added lateral stability.

Air Channel:
The air channel between the insert and the rim acts like a valve. During impact, some of the air molecules inside the tire move from the outer part of the insert to the channel, causing a pressure difference. Since the insert is very tight at the edge, these molecules get "trapped" and take a fraction longer to restore even pressure between the outer and inner parts. This means rolling resistance and tire bouncing are reduced. These two features together create what every cyclist seeks: EFFICIENCY.

During the first installation, we recommend not applying sealant to the valve.
