Eclipse TPU Gravel GT Inner Tube | 28" | 30-45 mm

Eclipse GT - Gran Turismo TPU inner tube

Designed for cyclists who demand top performance on every ride, this tube is ideal for tire sizes 622x30-45mm.

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

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 wide 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.
