Continental TPU Presta Inner Tube - 700c x 25-35c100mm

This Continental TPU Presta Inner Tube is a lightweight, space-saving solution designed for performance-focused road, gravel, and MTB riders who want dependable air retention with minimal weight. Its seven-layer TPU construction delivers a strong balance of durability, airtightness, and compact pack size, making it suitable for both daily use and as a premium spare.Key Features and Benefits:Seven-layer micrometre-thick TPU construction: Multiple sealed TPU layers work together to limit air loss and resist puncture stress, delivering consistent pressure retention and reliable performance over long ride durations.High-grade, lightweight TPU material: The advanced TPU reduces overall tube weight without compromising strength, improving rolling efficiency while keeping the tube robust enough for mixed road and off-road use.Uncoloured TPU finish: By avoiding dyes, the tube reduces the risk of surface imperfections that can affect sealing, resulting in more stable air retention and predictable inflation behaviour.Post-production quality inspection: Each tube is checked after manufacturing to ensure material integrity and consistent sealing, lowering the risk of early failures and pressure loss.Conical valve base design: The slightly tapered valve base improves the interface between tube and rim, reducing movement at the valve hole and helping maintain a secure, stable fit.Internally threaded Presta valve: Internal threading allows the use of valve extensions or a replaceable valve core, improving compatibility with deep rims and extending service life.This inner tube supports riders who prioritise low weight, compact storage, and dependable pressure stability across varied terrain. The combination of layered TPU construction, controlled manufacturing checks, and refined valve design results in a tube that holds air reliably while remaining easy to pack and maintain.Choose this tube as a practical upgrade for reducing rotational weight and maximising efficiency, while keeping a durable, compact solution ready for both regular riding and essential spares.
