Bike Tubes Buying Guide
Probably the most common replacement on any bike , bike tubes are liners that hold the air inside your tyres . Also known as inner tubes , these balloons are usually doughnut-shaped and have a valve for inflation that is designed to prevent any air leakage. Check out the different style bike tubes--they often vary by material and valve design--to see which is best suited for your normal riding routine.
The two main materials that bike tubes are made of are butyl and latex. Before World War II, tyres and tubes were made from natural latex rubber that was harvested from tropical trees. But once the war began, the supply became insecure and scientists worked to make synthetic latex materials that could measure up to the real deal. They came up with a more than adequate substitute called butyl, which was actually better for creating tyres and tubes than the natural latex that once inspired its creation. Today, most riders prefer this butyl rubber because tubes and tyres made from it are not as porous as latex, and they do not need to have their pressure topped off as often. Some people, however, prefer to stick to latex inner tubes specifically because they can be a little bit lighter than butyl and tend to have less rolling resistance.
