Size: 32 mm (normal valves) bike inner tube 1.75/1.95/2.125 fit 20 inch wheel mount.
High Quality: The bicycle tube is made of high-quality butyl rubber. It has the advantages of good sealing performance, ozone resistance, ageing resistance, shock absorption and electrical insulation.
Easy Installation: The installation is quick and easy. Please follow the inflation instructions when you are airing a tyre from a flat tyre. Save time and effort, replace the old tube in minutes.
Important Note: When changing a bicycle tube, make sure to add some air before installation. This gives it shape so it does not twist or bunch, which can lead to a squeeze. Check for a uniform bead of the tyre to the rim on both sides.
Comfortable and Safe: After replacing the butyl rubber hose, it absorbs the impact on the uneven road surface and makes driving more comfortable and safer.
