Tubolight Diamana XHD 27 Descenso

TUBOLIGHT DIAMANA XHD 27.5

Introducing Diamana, the most advanced tire insert ever created, offering an "unfair advantage" according to our professional riders. For the first time in history, the movement of air molecules inside the tire during casing deformation has been studied, ensuring, thanks to the insert, that tire pressure remains constant on the ground, significantly improving traction.

The side channels are designed to create a Venturi effect, accelerating airflow from the outer part of the insert to the inner part, similar to the ground effect in Formula 1 cars. The top surface, with dimples inspired by golf balls, ensures that air flows into the side channels, eliminating the strong rebound effect.

The results are impressive: rolling resistance on rough surfaces is reduced by up to 9%, even considering the additional weight of the inserts, translating into faster climbing speed. Tire pressure on the ground increases by 60%, taking traction to a whole new level.

Additionally, vibration damping improves by 55%, reducing fatigue and providing a more stable ride. Made from high-density closed-cell EVA foam, Diamana ensures constant airflow and exceptional durability, with a lifespan of years before needing replacement. Installation is simple and it is compatible with all sealants on the market without the need for specific valves.
