Chromoly steel frame. Chromoly is responsive and offers good flex while maintaining its form. A chromoly or really any steel bike frame will have a more compliant ride which means basically that it will be a smoother ride because the steel frame will absorb more of the road vibration. Alloying elements include chromium and molybdenum and as a result these materials are often informally referred to as chromoly steel common variant stylings include chrome moly cro moly crmo crmo cr moly and similar. This translates to sleeker frames faster speeds and comfortable maneuverability.
Chromoly chrome molybdenum steel a workhorse of the industry chromoly is a light strong steel. When it is butted and shaped to take off excess weight it can deliver a fairly light frame that will last through years of hard use. What is chromoly steel. Chromoly is a chrome alloy steel with a medium carbon content and 8 1 1 molybdenum for strength.
The steel bike frame will also be stronger and more durable than an aluminum frame. Chromoly steel is also much lighter than average steel while still maintaining similar strength. Chromoly steel is often used when more strength is required than that of mild carbon steel though it often comes at an increase in cost.
