Calfee Design builds the Tetra and Dragonfly Tandem bicycles to meet each rider's specific needs. Company founder Craig Calfee and his team work to assure that every specification matches the requirements of a particular tandem team. The Calfee name guarantees top quality, durability and superb craftsmanship using high technology materials.

The new lateral-less frame is a design triumph that succeeds in all three areas that a new frame design tries to achieve: Lighter, Stiffer and Less Costly. Usually, you are lucky to get only one of the three! The new design has been road tested and proven for teams weighing up to 400 pounds. It is theoretically capable of withstanding heavier teams.
