Our classic frame; an original optimized for perfection over 24 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 24 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.
Even bicycle enthusiasts and industry insiders are surprised to learn that Tetra was invented back in 1987 and only four years later was being ridden by Greg LeMond and his Team Z teammates in the world’s most important cycling event, the Tour de France. Greg wore the leader’s Yellow Jersey aboard our Tetra, then less than five years old. Today, nearly 20 years later, Tetra tubing and bicycle frames have been continually optimized; sharpened by improvements in raw materials, manufacturing processes and advantageous frame options.
With the Tetra frames, we saturate carbon fabric with epoxy, then laminate it at 210 p.s.i. and fuse it to pre-mitered carbon tubes using metal dies. Molded in one layup, the resulting joints have long tapered transitions from one tube to the next, following the stresses evenly. This manufacturing process seamlessly marries our tension filament wound carbon tubing resulting in a frame without molded lugs. Fatigue life for these fiber reinforced joints is appreciably longer than that of adhesive bonds and, coupled with the tubing itself, is grounds for the Tetra’s 25 year warranty. Read more here.
