Package Include:
4Pcs 28 700x23-25C Bike Tubes
4Pcs Tire Levers
Before installing, check to see if the inner tubes are completely sealed by putting them in water, if there are any bubbles, they are already damaged. We will provide a 100% refund or Free replacement to you soon.
1. Please kindly confirm the size of your bike tire before you buy, width between 23mm-25mm tires.
2. Before changing the tube, please check whether have some stones or sharp things that may break the tube that stay in your tire.
3. Remember to always add a little air (to give the tube form) to the new inner tube before installing it. This will prevent it from bunching up and/or causing a pinch flat or possibly blowing the tire off the rim (when you immediately and fully inflate) which ultimately will pop the tube.
4. The pressure rating is dependent on the PSI rating of your tire. DO NOT inflate the above pressure rating on the tire!
