Ultralight Bicycle Tube made of TPU 46 g 700×35C–50C with 65 mm French Valve for Road, Gravel and Mountain Bikes 29"
This ultralight tube made of thermoplastic polyurethane (TPU) represents a modern and durable solution for all types of bikes – road, gravel and mountain bikes with a size of 29". Thanks to its universal size 700×35C–50C (29×1.5 to 29×1.95), it adapts to a wide range of tyres and provides the ideal balance between weight, durability and performance.
With a weight of only 46 grams, this tube is significantly lighter than standard rubber variants and helps reduce the overall weight of the bike. This contributes to smoother acceleration, better handling and more efficient riding. The TPU (thermoplastic polyurethane) material ensures high elasticity, strength and puncture resistance, while maintaining stable pressure even with prolonged use.
This variant is equipped with a 65 mm French valve (Presta), which is particularly suitable for high-profile rims and allows for easy inflation and precise pressure measurement. The valve features reliable sealing and simple operation. Due to its compact size, the tube can be easily folded and carried as a spare in a pocket or bag.

When installing, we recommend slightly inflating the tube (to about 0.5 bar / 5 PSI) to ensure it settles correctly in the tyre. Never inflate it outside the circumference of the wheel – there is a risk of permanent damage or deformation. Use a hand pump, not a compressor or electric pump, which can cause overheating of the material.
This TPU tube represents the ideal choice for cyclists who require low weight, high durability and long lifespan. It offers a smoother ride, lower rolling resistance and reliable performance on every journey. Thanks to its design and quality valve, it is suitable for both everyday use and sport and racing rides.
