Eclipse Off-Road GT Inner Tube - 29" - ETRTO 622mm (700C) | 40-65 mm

The original ultra-light TPU bicycle tube - Lightweight and small, the perfect companion

Unsurpassed durability and lightweight design: The Eclipse TPU off-road tubes are made of high-quality thermoplastic polyurethane (TPU) and offer an exceptional balance between durability and lightness. These tubes are up to 60% lighter than traditional butyl tubes, improving your bike's performance and maneuverability on difficult terrain.

Superior puncture resistance: Developed for the most demanding off-road conditions, the unique TPU composition of Eclipse tubes offers exceptional puncture and cut resistance. Ride with confidence on rocky trails, muddy paths and uneven terrain. You can be sure that these tubes are up to the challenge.

Exceptional flexibility and adaptation to the terrain: The high elasticity of the TPU material ensures that Eclipse off-road tubes adapt perfectly to the terrain, providing excellent traction and control. Whether you're riding steep hills, loose gravel or forest trails, these tubes improve the grip and stability of your bike.

Environmentally conscious and fully recyclable: Eclipse TPU off-road tubes are designed for sustainability. Not only are they durable, but they are also fully recyclable, making them an eco-friendly choice for environmentally conscious riders.

GT - Gran Turismo

Eclipse TPU tubes labeled as Gran Turismo or GT are characterized by the following features:

Durability
These tubes are made from reinforced TPU material to withstand punctures, wear and long use on rough or mixed surfaces. This makes them ideal for touring riders who may encounter a variety of road conditions over long distances.

Comfort and flexibility
GT tubes are designed to provide a smooth and comfortable ride by keeping the tire pressure, and therefore the cushioning, constant for longer. This better compensates for bumps in the road and minimizes driver fatigue - crucial for long-distance driving.

Greater airtightness
Gran Turismo tubes are designed to maintain air pressure over longer periods of time and require less frequent re-inflation. This feature is particularly important for riders who cover hundreds or thousands of kilometers on a single ride and use their bike regularly.

Compatibility
Eclipse TPU tubes are compatible with a wide range of tire sizes and types, especially those used on touring or adventure bikes. They are versatile and capable of handling different loads as well as changing road conditions.

Do you know TPU?

Thermoplastic polyurethane (TPU) is a versatile thermoplastic elastomer that bridges the gap between rubber and plastic. It has been commercialized since the 1950s, but has gained a lot of importance in the last 15 years. TPU is known for its high elasticity, flexibility, durability and abrasion resistance, making it the material of choice in several sports applications, such as bicycle grips and inner tubes. The Eclipse TPU material can be stretched by over 400% before it fails. Modern TPU is a highly sustainable material that can be recycled and reused without significantly losing its material properties. It is therefore ready to take on a leading role in future material developments.
