Craig Calfee‘s new Tetra Adventure Classic was just one of the bikes we were looking forward to seeing up close at the postponed North American Handmade Bicycle Show. Calfee is of course the famous NorCal builder who made carbon fiber history when he supplied Greg LeMond and the Z Team with a fleet of his full carbon frames in the 1991 Tour de France.
Fast forward nearly three decades later and Craig and his team of carbon artisans have now modernized the classic Tetra frame into something with a more accurate interpretation of contemporary technology and design. No, not a gravel bike, although it could be. In typical Calfee ingenuity and open-mindedness, the Tetra Adventure Classic frame can be specified in either Pro (road) or Adventure (gravel) guise. As with all things Calfee, customization runs in accordance with a legacy of artisan craftsmanship.
From the variety of models found on the Calfee Designs menu, the Tetra is one that relies on the small diameter tubes like the original Tetra, only now they use both a higher modulus construction with an advanced lay-up schedule.
The beautiful webbed lugs are all hand molded and add a distinctive signature to the bike. In addition to the Whiskey Parts carbon fork, new too are the solid and flattened carbon chainstays to bring some added compliance.
