For nearly 30 years, we have been building superior carbon frames, with stock and custom geometry, for tall cyclists.

We offer carbon frames in stock geometry up to size 68cm.  A tall cyclist is further supported by our custom frame program; in this case, we can achieve any and all critical frame metrics to perfectly position the rider.  Additionally, we use size specific tubing to tune ride characteristics, ensuring that a big bike frame is stiff enough and that a smaller is not overly harsh.  Furthermore, our elongated carbon tubing is optimized for strength and frame stiffness, eliminating fatigue and flex, respectively.

Pictured above (frameset) and below (Tim’s complete bike); 68cm Calfee Manta Pro with a 30cm long head tube.  This is an example of our largest stock frame size. Riders requiring a bigger frame are supported by our custom frame program.

In considering which big bike frame to buy, you’ll first need to consider frame material.  Why carbon fiber?  Given carbon’s inherent qualities, why not?  From our Technical White Paper:  Carbon fiber exhibits the most desirable performance characteristics of any of the frame-building materials explored to date.   It can be designed to be laterally stiff under heavy pedaling forces and still be light. It can absorb road shocks well, and still handle crisply while efficiently delivering complete power to the drive train. It can be durable and not subject to fatigue failures while remaining strong enough to stand up to unexpected impacts and torsion forces. It can lend itself to attractive finishing and resist corrosion or attack by the elements. And it can be formed in an attractive, functional way allowing it to move through air resistance easily.  In summary; a bike frame with carbon fiber tubing can be stronger, lighter, stiffer, more fatigue resistant and more comfortable than a steel, aluminum, magnesium, titanium or hybrid-carbon tubing bicycle.  Our frame design leverages the beneficial and intrinsic attributes of the carbon fiber material to manifest the best riding, and looking, big bicycle frames in the world.

Our Manta Pro is a popular frame platform for tall cyclists; riders particularly enjoy the stiffness, and aesthetic, resultant from the very large diameter carbon tubes.  Ready to discover the difference?  Visit our factory for a complimentary sizing session aboard our Sizer Cycle, visit 3D Bike Fit or one of our excellent retailers.



44, What’s it for?

What is the idea behind the new 44 models you ask?  Our classic model types, Dragonfly, Tetra, and Luna, are now available with 44mm head tube diameters and a matching oversized down tube.  These changes create capability with tapered steerer … Continue reading
