NOTE:
1. Please kindly confirm the size of your bike tire before you buy
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, Not to exceed 2 PSI) to the new inner tube before installing it, and check the bicycle tube is intact. 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. Never over-inflate

Presta valve is better air tightness and more durable than schrader valve
