Why Chromoly?

Why Chromoly?

Chromoly is much stronger than traditional steel and aluminum alloys. Chromoly is the most earth friendly material that we’ve seen besides bamboo that’s being made into bicycles. Studies show that chromoly requires 6-11 times less energy and emissions than competing materials to mine, manufacture and process.

Most people looking to buy our frame will have their minds made up on chromoly steel frames and prefer this material for their next frame but if you’re new to or curious about this amazing material, here are some of the advantages you’ll hear from experienced riders:


Chromoly steel bike frames possess a natural flex that absorbs sounds. While not completely silent when contact is made with rocks or roost, the ride is very stately feeling. Focus on the path ahead, not nuisances.


You’re buying a bike that will stand the test of time with proper care and maintenance. Imagine owning a bike that can be welded and repaired rather than degrade and be thrown away. Most people consider the user-friendly nature of chromoly to be a very wise investment.


Our steel full suspension mountain bike frames are engineered with controlled flex, working with the natural characteristics of heat treated chromoly and stiffening it up where it’s necessary for maximum efficiency. Chromoly tubing for a mountain bike is very thin yet incredibly strong, it has an inherent flex that people strive for in order to reduce vibrations translated to their hands and feet which works to reduce rider fatigue and increase rider comfort. Ride longer, more comfortably and much harder. Slight flex in the rear keeps the wheel planted in sharp hard turns keeping you on two wheels.


Chromoly’s strength to weight ratio rivals that of titanium yet it’s more affordable. Rest easy knowing what you’ve accepted as norm, steel is strong. Imagine a high-tech, lighter weight yet stronger alloy of steel being made into a frame for your next mountain bike. There are pluses and minuses for every known material being made into a mountain bike frame but welded seems, not glued, is something we personal feel is more solid and secure. Metal melted to metal, not piece, glued to piece. Fancy marketing words will lead you to believe other materials are “one solid piece” (“Monocoque”) but research shows that’s misleading, it’s actually multiple segments glued together into one piece which is strong too for only a comparably very short lifespan. Ride safe though, we can’t be held responsible for your new found feel of steel, ride at your own risk, ride responsible.
