Tetra With Two Sets of Couplers

Our tandem frames, as light as the very lightest aluminum, titanium and hybrid-carbon frames from our competitors, set a new standard for comfort, durability, beauty, lateral-stiffness and power transmission.  We are doing for the tandem world today 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.

Notably, we offer a double Gates belt drive option; you can pair a Rohloff internally geared hub with a Gates drive and timing belt.
