Hycline's 700Cx25C/28C and 32C/35C bicycle inner tube is a perfect fit for most road or mountain bikes, and is equipped with a 48mm Presta valve for easy use. Made of premium butyl rubber material, it has excellent sealing, heat resistance and durability, suitable for any season and weather conditions.

The inner tube kit comes with two tire levers for quick inflation and deflation, making it an ideal choice for daily replacement on mountain bikes, kids bikes, commuter bikes and tricycles. It can effectively absorb road vibrations and shocks, providing you with a comfortable riding experience and excellent handling performance.

Here are some warm tips and precautions to make sure you mount and use your new bicycle inner tube safely:

1. Please confirm the size of your bicycle tire before purchasing.
2. Before inserting the new inner tube, please be sure to check if there are any sharp objects inside the tire to avoid puncturing the inner tube.
3. Before installation, inflate the new inner tube slightly (to shape the inner tube). This will prevent the inner tube from curling, causing tire compression or forcing the tire to detach from the rim.
4. Insert the valve stem through the hole in the rim. The valve stem should protrude at a 90-degree angle. Tighten the valve stem cap securely.
5. After installation, ensure that the valve stem is fully inserted into the tire and not caught between the tire and the metal frame. You can now inflate the tire to the recommended pressure level.
