What element is used in bike frames?

Answer 1

It depends on which bicycle you are speaking about. The general ones are made of steel or aluminium(lighter bicycles).

If you go for mareda and the higher brands of sports cycle then they are made up of carbon fiber.

Answer 2

Can be steel, usually Cr-Mo. Can also be aluminum, or aluminum alloys. Some are titanium. There are also carbon fibre frames, which are carbon and "plastic".

In the future , Titanium will be replace other materials.

For some uses, perhaps. For all uses, very unlikely.

Ti is quite expensive and more flexible, springy than steel. In some applications this is useful, in other it's a problem.

Many bikers buy the titanium bolts instead of stainless steel bolts and aluminum screws. Titanium fasteners are very strong, rustproof, and light.

But Ti fasteners are pretty much only good for lightly loaded assemblies.

When exposed to the same force a Ti bolt will stretch more than a steel bolt of the same size, making it possible for whatever part it's attaching to wiggle around as if it was loose. Pretty much like having your shoes tied on with rubber bands. They'd fit snugly when you're just standing around, but if you were to launch into a sprint your feet would come right out.

To make a Ti bolt that can clamp down as hard as a steel bolt it has to be made bigger, which makes it heavier, which robs it of its advantage against steel. But it's still a better choice that aluminum fasteners.
