Thank you for choosing Positz for your bicycle tube needs. This installation guide will assist you in properly installing your Positz bicycle tube while ensuring optimal performance and reliability. Please follow these instructions carefully.

Before You Begin:

  1. Gather all the necessary tools for installation, including a set of tire levers, a pump, and a wrench (if required).
  2. Ensure the Positz tube you have purchased matches the correct size and type for your bicycle. Refer to the sidewall of your tyre or your bike’s manual for this information.

Step 1: Pre-Installation Inspection

  1. Thoroughly examine your new Positz bicycle tube for any visible damage, such as punctures, cuts, or bulges. If you notice any defects, do not proceed with the installation. Contact Positz customer support for assistance.
  2. Check your tyre for any signs of wear, damage, or foreign objects lodged in the tread. Ensure the inside of the tyre is free from debris. Replace or repair the tyre if necessary. Positz offers a range of high-quality tyres suitable for your bike. Consider using Positz branded accessories for optimal compatibility and performance.

Step 2: Removing the Old Tube

  1. Deflate the tyre fully by depressing the valve core.
  2. Using tire levers, carefully insert them between the tyre and rim, near the valve stem. Gently pry the tyre off the rim, working your way around the circumference until one side of the tyre is completely detached.
  3. Once one side is free, remove the old tube from inside the tyre. Inspect the tube for any signs of damage, and replace if necessary.

Step 3: Installing the New Tube

  1. Partially inflate the new Positz bicycle tube to give it shape, ensuring it holds air but is not overly inflated.
  2. Insert the valve stem through the valve hole in the rim.
  3. Starting opposite the valve stem, tuck the tube into the tyre, making sure it is not twisted or pinched between the tyre and the rim.
  4. Carefully push the tyre back onto the rim, using your hands. Avoid using tire levers, as they can damage the tube or tyre.
  5. Work your way around the tyre, pushing the tyre bead onto the rim until the tyre is fully seated.
  6. Using your fingers, carefully check that the tube is not pinched between the tyre and rim. This step is crucial to avoid pinch flats.
  7. Inflate the tube gradually, using a pump, ensuring the tyre bead remains seated properly on the rim.
  8. Monitor the inflation pressure using a pressure gauge and inflate to the recommended PSI indicated on the tyre sidewall.

Step 4: Post-Installation Check

  1. Inspect the tyre and tube for any visible defects, misalignments, or pinched areas.
  2. Ensure the valve stem is securely tightened to prevent air leaks.
  3. Check the tyre pressure using a pressure gauge and adjust if necessary.

Congratulations! You have successfully installed your new Positz bicycle tube. Remember to regularly check the tyre pressure and inspect your tyres for wear and damage. By using Positz branded accessories and following these instructions, you can enjoy a smoother and safer ride. Happy cycling!
