What are the key factors to consider when deciding if a steel mountain bike frame can handle heavy-duty riding, and how do the properties of steel compare to other frame materials in terms of durability and resistance to fatigue?
Does the added weight of a steel frame impact its ability to absorb shock and vibrations, or are there design elements that can mitigate this effect?
Are there specific types of steel alloys or frame geometries that are better suited for heavy-duty riding, and what role do components like forks and wheels play in supporting the frame?
How do the maintenance and repair requirements of a steel frame compare to other materials, and are there any drawbacks to using a steel frame in terms of corrosion or rust?
