Calfee Tetra HT Tandem – Premium Build




IMG_4296Calfee carbon tandem frames are the frames against which all others are measured; the benchmark in comfort, speed, fun, value and beauty.


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

Why carbon fiber? Given carbon’s inherent qualities, why not? 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 carbon fiber tube bike can be stronger, lighter, stiffer, more fatigue resistant and more comfortable than a steel, aluminum, titanium or hybrid-carbon tubing bicycle. Calfee tandem frame design leverages the beneficial and intrinsic attributes of the carbon fiber material to manifest the best riding, and looking, tandem bicycles in the world.
