Featherweight and Durable: Made with advanced Thermoplastic Polyurethane (TPU) technology, these tubes weigh just 36g (700×18-32C) and 45g (700×32-47C). They offer the perfect balance of durability and lightweight design, ideal for competitive racing and everyday riding.
【Major Upgrade①: Metal Presta Valve】TPU inner tubes typically use lightweight plastic valve stems, which can lack airtightness and occasionally cause leaks. RideNow addresses this issue by using metal valve stems, maintaining a total weight of just 36g (700×18-32c) and 45g (700×32-47c). This upgrade ensures a reliable ultra-light experience with improved air tightness. The metal valves are also more corrosion-resistant, providing stability during rides.
【Major Upgrade②: Removable Core】The removable valve core design allows for easy maintenance and replacement of the air core at any time. It is also compatible with threaded extension nozzles, offering added convenience for users.
Two Sizes Available: 700×18-32C and 700×32-47C. If your road bike tire size is 700x18C, 700x23C, 700x25C, 700x28C, or 700x32C, choose 700×18-32C. If your gravel bike tire size is 700x32C, 700x35C, 700x37C, 700x40C, or 700x47C, choose 700×32-47C.
Multiple Valve Length Options: Available in 45mm, 65mm, and 85mm Presta valves, you can choose the perfect valve length to match your bike’s rims.
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.
