Tetra - Frame

Our classic frame; an original optimized for perfection over 23 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 last 23 years. As the oldest continuously produced model of carbon fiber bicycle frame in the world, it has evolved to a state of perfection and value unmatched by any other frame.

The precise orientation of the Tetra’s 51 million fibers delivers the best combination of stiffness and comfort for everyday riding.  While these frames are unbelievably stiff through the drive train and are very light (2.4 pounds for a 54cm single and 6.8 pounds for a Medium/Small tandem), they are especially easy on the saddle and handlebars.  These qualities conspire to make Tetra the choice of traveling tandem teams, privateer racers, endurance road riders and gravel-road randonees.
