Steel is great. It is flexible, providing road-feel. And it is strong. But, it is prone to rust. At Simplicity Bike we prefer any exposed steel to be stainless steel. Our restored steel frames are stripped to bare metal and given two coats of primer and two coats of finish paint.
We love aluminum. One, because it doesn’t rust, and two, because it is lighter than steel. We prefer aluminum wheels whenever possible.
Rust example. Even with chrome coating, rust happens.
