Traction, Power, and Comfort

The Manta is a “race platform” that leverages a patented, active suspension system at the rear wheel to enhance traction, power transmission and comfort to increase rider performance.

Perfection and Value

Our road frames were born in 1987, tested in the Tour de France in 1991, and optimized every year since; sharpened by improvements in raw materials, manufacturing processes and advantageous frame options. They have evolved to a state of perfection and value unmatched by any other frame.

Calfee Adventure

“As more and more research finds that wider tires offer not only better comfort and safety, but also better performance, I consider the Calfee Adventure the racing bike of the future.”

– Jan Heine, editor, Bicycle Quarterly, Autumn 2011

“…as good as it gets…”

“…brilliant design and construction mated to a fantastic ride, made in America with a certifiable sense of brand prestige, and all with a 25 year warranty.  In short, the Calfee Dragonfly is as good as it gets.”
– Road Bike Action, May 2011

29er Tetra Gravel/MTB Tandem

Our 29er Tetra tandem frame design leverages the beneficial and intrinsic attributes of carbon fiber material to realize the highest performance off road tandem available; now available with rear suspension.

Tetra & Dragonfly Tandems

You no longer have to compromise. Our tandem frames, as light as the very lightest aluminum, titanium and carbon frames from our competitors, set a new standard for durability, power transmission and lateral stiffness. We are doing for the tandem world in 2011 what we did for the single world in 1987; building a lighter, stronger, stiffer more absorbent frame that is faster and more fun to ride.

Calfee Bamboo

Our bamboo bicycle frames are very stiff, transferring power efficiently; are durable, resisting damage from stress and impacts; are comfortable, surpassing aluminum, steel, titanium and most carbon frames in smoothness.

Single Speed, Belt Drive & Internal Gears

All our frame models, carbon and bamboo, are ready to run a single gear, free or fixed.  To tension the chain or carbon belt, choose a horizontal dropout or an eccentric bottom bracket shell.  The Rohloff 14 speed internal hub is also a popular option.
