• Featherweight and Durable: Made with advanced Thermoplastic Polyurethane (TPU) technology, these tubes weigh just 36g (700x18-32C) and 45g (700x32-47C). They offer the perfect balance of durability and lightweight design, ideal for competitive racing and everyday riding.
• Versatile and Cost-Effective Compatibility: Designed for both disc and rim brake systems, these innovative inner tubes suit a wide range of road bikes. They provide exceptional puncture resistance and maintain stable performance even at lower tire pressures, making them ideal for challenging racing and riding conditions.
• Proper Inflation Guidelines: To avoid damage, do not overinflate the inner tube when it’s not installed in the tire. During installation, start with an initial inflation under 0.5 Bar/8 Psi. Ensure the inner wall of the wheel and tire is clean before installation to prevent foreign objects from puncturing the TPU inner tube.
