🧩 RideNow MTB Bike TPU Inner Tube is the ultimate choice for serious mountain bikers who demand performance and reliability on every ride. Designed specifically for 29-inch wheels (29/622) and compatible with tire widths ranging from 1.9 to 2.5 inches, this ultra-light inner tube weighs in at just 56g, ensuring minimal weight without sacrificing durability.
🏔️ This inner tube features a Presta valve stem with a 45mm length, ensuring easy installation and compatibility with a wide range of rims. Its construction from high-quality TPU (thermoplastic polyurethane) guarantees excellent resistance to punctures and tears, allowing you to tackle rugged terrains with confidence.
🪶 Before inflating your RideNow tube, it is essential to adhere to specific guidelines to maintain the integrity of the product. The inner tube should only be inflated once it is installed within the outer tire. Always use a manual air pump to inflate the tube, as high-speed air-filling equipment can lead to irreversible damage.
🧩 For the initial inflation, gently turn the valve inward towards the center of the wheel, and pump in a small amount of air until the tube takes a rounded shape; ensure the pressure remains below 0.5 bar (8 PSI) at this stage. It is crucial to monitor the application of pressure—never exceed 5 bar (72 PSI) if your rim uses a no-ring-lip system as defined by ISO/TC 31.
🧩 Keep in mind that temperature fluctuations can affect tire pressure. For every 3°C (5°F) rise in temperature, expect an increase of approximately 1% in tire pressure. If you inflate tires in cooler conditions and ride in significantly warmer environments, such as on hot asphalt exceeding 65°C (150°F), the resultant pressure could exceed the safe limit, posing a risk of tire separation from the rim and potential injury.
💍 Finally, if storing pneumatic tires in high-temperature areas, such as inside a car on a hot day (60°C / 140°F or higher), it is advisable to reduce the inner tube pressure to about 1 bar (15 PSI) to prevent valve deformation and ensure longevity.
