Calfee Tandems

Calfee Tandems

Beautifully formed by our carbon craftsmen

You no longer have to compromise. Our tandem frames, as light as the very lightest aluminum, titanium and carbon frames from our competitors, set a new standard for durability, power transmission and lateral stiffness. We are doing for the tandem world in 2018 what we did for the single world in 1987; building a lighter, stronger, stiffer more absorbent frame that is faster and more fun to ride.

Dragonfly Tandem

Tetra Tandem Blue Coupled4

Tetra Tandem

Our 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. Very simply, the best tandem bicycles in the world.

Off Road Tandem

Off-Road Tandem

Calfee Design worked diligently to deliver you the most advantageous full suspension & front suspension off-road tandem platform in production. The ideal off-road tandem frame for a given team would fit the rider’s build, is very light and will absorb shock well. The Tetra Tandem handles crisply because of lateral stiffness and would deliver undiminished applied pedal power to the drive train. Off-Road Tandems are durable and not subject to fatigue failures and are strong enough to stand up to unexpected impacts and torsion forces.

Bamboo Tandem

Bamboo Tandem

There are many good reasons to choose Calfee Bamboo for your next tandem bicycle frame. Calfee Bamboo bicycle frames are very stiff, transferring power efficiently; are durable, resisting damage from stress and impacts; are comfortable, surpassing aluminum, steel, titanium and most carbon frames in smoothness. Our bamboo tubes mitered together and bound by epoxy soaked hemp fiber create a frame whose most notable characteristic, beyond beauty, is this incredible vibration dampening.

Tandem Tetra Fat Tire

Tetra Fat Bike Tandem

This carbon fiber model is right at home on any terrain; sand, dirt, snow, including tens of thousands of miles of shoreline!

Tandem Convert

Tetra Convertible

We are excited to introduce a new model in our line of performance tandems, the Tetra Convertible.  This adaptable platform is wholly functional as both a tandem and single bicycle. Precisely located S&S Couplings allow for the easy removal/addition of critical frame sections.  As well, component selection is optimized to support the very same.  A tandem team would enjoy a pedal as a pair one day, and the very next, one or both riders as solo cyclists.
