The Soul of Steel

A Ride Like No Other
There's a tangible character to a steel bike that you have to feel to understand. The Double-Butted 4130 Chromoly frame is the heart of this machine, engineered to be both strong and forgiving. Feel how it mutes the high-frequency road chatter, taking the edge off of rough surfaces and reducing fatigue on long rides. Sense its lively, "springy" feedback as you accelerate and carve through corners. It’s a dynamic, comfortable, and deeply engaging ride that connects you to your journey.
Versatility, Redefined

One Bike, Any Road
This is our most capable 4130 Steel Line yet. The redesigned frame now has clearance for tires up to 45c, transforming it from a classic road bike into a versatile all-road weapon. Feel the plush, confident grip of wider tires as you float over cracked pavement and hard-packed dirt that would rattle a traditional road bike. It’s a tangible sense of freedom that allows you to choose your path, not be limited by it. Pavement, potholes, or gravel—this bike is ready.
