Alloy. Specialized Allez â one of the best selling alloy bike on the market. Alloy is bicycle business shorthand for aluminium alloy. An alloy is a solid solution made of metal, and another element â the metal in this case being aluminium.A high proportion of bikes are made of aluminium alloy â itâs an easy material to manipulate into an efficient shape, and itâs the cheapest way to make a relatively light bike.teel bike owners generally love steel bikes, and their bikes can last a lifetime kept in the right hands. The material will rust if not cared for, but it wonât fatigue like alloy and is very hard wearing.
And there are carbon fiber bikes too. Different metals are used for different bicycle frames. The cheapest metal used is would be a high tensile carbon steel. Better steel bicycles are made of chromoly steel, which is an alloy of steel with chromium and molybdenum.This alloy makes the steel stronger and harder than cheaper steels.Steel frames can also have butted tubes.he cheapest metal used is would be a high tensile carbon steel.
