Calfee Tetra Classic Road Bike

The original optimized for perfection over 25 years

The Tetra tube set and single, road frame was originally designed in 1987 and has been thoughtfully refined to its current incarnation over the years. In 1991, when asked if he’d like anything different in regards to frame stiffness or ride quality, Greg LeMond said: “Don’t change a thing. It’s perfect.”
