Dahon Tournado earlier model. This bike uses Ritchey Breakaway patented system. Actually Dahon used to sell a Breakaway road bike called Allegro but now they sell Tournado targeting the touring cyclists. The only notable difference with the current model is that the the photographed model has long reach dual pivot caliper brakes rather than canti / V-brake setup. Canti is preferred option by the traditionalist who want a separable / packable randonneur. This is one of the few commercially available touring bike that won’t require upgrades or swapping components to go on a long trip. A very under-appreciated masterpiece that deserves more popularity.
