Le Duo











The LE DUO tandem is an adaptable tandem platform, ready for racing, touring, or something entirely unique (gravel tandem anyone?).  It is the fruit of a long history building tandems for French National Team riders, tourers, and passionate cyclists the world over.  Light, stiff, resilient and a pleasure to ride, the LE DUO is the real deal in tandem.  Pairing our skill with alloy construction together with an amazing ability to provide full customization, the LE DUO offers arguably the most-varied canvas upon which to craft your tandem dream. 

Available exclusively in custom geometry.

Available in two grades of alloy, NERV and ZONAL.
