Which is stronger and lighter for a bike frame chromoly or steel?
For a bike frame
Same basic material. For example, Reynolds 520 Butted Chromoly is a form of steel.
Chro-Moly
“Chro-moly is a fancy name for steel. Steel is heavy. But, steel is stiff. A frame made with chro-moly will usually have small tubes. To help reduce weight many steel frames have thin walled tubes. But remember, the thinner the tube walls are the less stiffness you’ll have. If you’re a heavy rider you’ll want a thicker tube wall to support your weight. Reynolds 853 is usually considered the best type of steel for bike frames because it gains strength as it cools after the welding process. All steel has the same inherent stiffness.”
