RideNow TPU 700C Road Bike Inner Tube

🛠️ Experience the precision and reliability of the RideNow TPU 700C Road Bike Inner Tube, designed for a range of tire sizes from 700x18 to 700x47, making it an ideal choice for diverse road cycling needs. Engineered with a French valve, this inner tube is compatible with tire sizes such as 27.5 and 26x1.5 through to 1.9, ensuring versatile performance across various wheel setups.

⚡ Important Usage Tips:

🔴 Maintain the integrity of your RideNow inner tube by avoiding over-inflation when it is outside the outer tire to prevent irreversible damage. For optimal results, employ a manual air pump for inflation. This ensures a controlled pressure increase and reduces the risk of damage caused by high-speed air filling equipment.

💍 When preparing the inner tube for use, adjust the valve by turning it inward towards the center before inflating. Begin by inflating the tube just enough to form a round shape, keeping the pressure below 0.5 bar/8 PSI.

💍 Adhering to tire inflation guidelines is crucial, especially with certain rim types. For rims adhering to ISO/TC 31 standards with a no-ring-lip system, do not exceed a tire inflation pressure of 5 bar/72 PSI.

Environmental Considerations:

💥 Temperature variations can significantly impact tire pressure. For instance, every 3°C (5°F) increase in temperature results in approximately a 1% increase in tire pressure. This means significant temperature changes, such as those experienced from morning rides in a cool garage to afternoon heat, can result in unexpected pressure fluctuations. High-temperature conditions, especially when cycling on asphalt with surface temperatures exceeding 65°C (150°F), can easily cause the tire pressure to surpass safe limits. This scenario increases the risk of tire separation from the rim, potentially leading to injuries.

🔴 In scenarios where pneumatic tires are stored in environments exceeding 60°C (140°F), such as inside a car on a hot day, it is advised to deflate the inner tube to about 1 bar/15 PSI. This precautionary measure helps prevent valve deformation and maintains the integrity of the inner tube.
