상품 특징

• 🚴 BLACK SEAL – PRESSURE RETENTION AND STRUCTURAL DURABILITY: This tpu inner tube 700c is engineered to address the most common TPU issues: gradual air loss, valve junction fatigue and seam stress. Black Seal combines premium 0.35 mm TPU, reinforced metal valve architecture and controlled seam compression to improve long-term pressure stability in tpu inner tubes.
• 🚴 TPU MATERIAL WITH ENHANCED STRUCTURAL RESISTANCE: This road bike inner tube significantly reduces rotating mass compared to a traditional butyl tube, helping lower rolling resistance. Black Seal adds material and reinforcements where lightweight TPU designs typically fail, providing a more stable and durable solution for riders choosing tpu tubes for road use.
• 🚴 REINFORCED METAL PRESTA VALVE SYSTEM: The 700c inner tube features a full metal Presta valve with removable core and anodized anti-corrosion finish. A pre-installed black rubber sealing ring reduces stress concentration at the TPU–valve interface, one of the most common causes of air loss in standard tpu tubes.
• 🚴 700C ROAD BIKE COMPATIBILITY WITH CONTROLLED EXPANSION: Designed as an inner tube 700C compatible with all common road sizes from 700x18C to 700x32C. This tpu tube 700c provides controlled expansion without internal tension, ensuring stable pressure behavior across tyre widths. Suitable for tpu tube, 700c tpu tube, tpu bike tube, and tpu bike tube 700c applications, offering a reliable fit for demanding training and everyday road riding without overstressing the TPU material.
• 🚴 SAFE INSTALLATION FOR TPU INNER TUBES: Lightly pre-inflate the bike inner tube (20–30%, max. 6 PSI) before installation to allow proper shaping. Insert the valve into the rim, position the tube evenly inside the tyre and inflate to the recommended pressure. Do not inflate outside the tyre or use metal levers. Full customer support included.
• 100% GUARANTEE: Customer satisfaction is our top priority. If you have any questions, experience any issues, or are not fully satisfied with the product, please contact us and we will be happy to help resolve it as quickly as possible.
