BulletPoint4 : When changing your bicycle inner tube ALWAYS be sure to add just a little air to the tube before installing. This gives it form so it doesn't get twisted or bunch up which may cause a pinch flat. Once the new tube is installed and BEFORE fully inflating only add a few PSI to further form the tube. Inspect for an even bead of the tire to the rim on both sides. BulletPoint5 : Then, inflate to approximately half the desired PSI and re-inspect the tire bead to the rim again. If even beading all the way around on both sides then inflate to the recommended air pressure. This procedure is important because if the bead doesn't hook properly on the rim then as the inner tube is inflated it can sneak out between the tire and rim and then BOOM! BulletPoint6 : Tip:Before installing the inner tube, please put the inner tube into the water for inspection, if there are bubbles, it means that it has been damaged, you can contact us. Check the valve position to ensure that the installation direction is correct. Note: The inflatable inner tube should avoid puncture by sharp objects BulletPoint7 : This heavy duty inner tube is compatible with the corresponding models of mountain bikes, road bikes, Cruiser bikes, electric bikes; At the same time, the increase in thickness can meet the needs of the longer driving range and load of the prevailing electric bicycles.

Sunlite tubes are high quality tubes at an affordable price. These tubes work on all brands and genres of bicycles. Verify the size you require. Replacement inner tube for road, recumbent, triathalon, mountain, single speed fixies, cruiser or any bicycle tire with the same tire dimensions. Be sure to verify the size of inner tube, valve type and length. 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.
