Tube TUBOLITO CX/GRAVEL/ALL 700x32/50mm FV/PV 60mm

Tube TUBOLITO CX/GRAVEL/ALL 700x32/50mm FV/PV 60mm

LIGHT. SUPER STRONG. COMPACT.

This inner tube weighs only 60g, significantly less than conventional inner tubes (100-150g). It is an ideal spare tube for CX / Gravel bikes (also compatible with tubeless systems), offering a highly compact solution. The Tubolito inner tube is as strong as a conventional inner tube, ensuring reliability in all conditions.

Tubolito inner tubes are made from thermoplastic elastomer (TPU), which provides excellent air retention – it holds air many times better than latex, while also being significantly more durable and lighter. Although latex tubes have slightly lower rolling resistance, Tubolito offers the world's lightest CX/Gravel inner tubes, also suitable for 27.5" wheels / 650B tires. They are heat-resistant, making them suitable for use with rim brakes, and can withstand sub-zero temperatures for everyday rides.

Maximum pressure: 8 BAR / 115 PSI. Without an outer tire, the inner tube should never be inflated to a pressure above 0.5 BAR. It's important to remember that the same inner tube is not designed for use with different sized outer tires, especially when switching from a larger to a smaller size, as it will not return to its original size after being under pressure.

Weight savings and economic advantage: By combining Tubolito inner tubes with a lightweight outer tire, you can save over 100g per wheel, even compared to tubeless setups. This is because TLR (Tubeless Ready) tires themselves weigh +100g more, plus sealant (50g), a special valve, and extra rim tape. Additionally, non-TLR outer tires are often more affordable.
