Tubolight Diamana XHD 29 + XHD 27 Descenso

TUBOLIGHT DIAMANA XHD 29 + XHD 27 DOWNHILL

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 that thanks to the insert, tire pressure remains constant on the ground, significantly improving traction.

The side channels are designed to create a Venturi effect, accelerating the airflow from the outer part of the insert to the inner part, similar to the ground effect in Formula 1 cars. The upper surface with golf ball-inspired dimples ensures that air flows into the side channels, eliminating the harsh 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 greater 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 consistent airflow and exceptional durability, with a lifespan of years before replacement is needed. Its installation is simple and it is compatible with all sealants on the market without the need for specific valves.

Diamana XHD New extra-durable size, hard compound designed to work specifically with heavy double-layer tires. Applications: enduro, downhill, e-bikes. Weight: 205 grams (27.5”), 220 grams (29”).
