PS-- 1.Please kindly confirm the size of your bicycle tire before you buy. If you buy tubes are not the right size, you may return the products for a full refund. 2. Before changing the tube, please check whether have some stones or sharp things that may broke 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. 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 past the recommended tire pressure.
