Doppo Ronin is a bicycle frame that most completely embodies the spirit of the Doppo series of frame models from SimWorks. It was renamed to ‘Ronin’ following a model update from the previous ATB and has continually evolved with each update to remain a practical tool, with subtle new features in refinement. These new features include our original rear dropouts and a reshaping of the seat stays.

The name Ronin (浪人) signifies “wandering the world without being bound by anything.” This ethos is reflected in its design, emphasizing versatility within the many standards and conventions of an ever evolving bicycle landscape. It accommodates a wide range of preferred configurations and tire sizes, offering greater flexibility. The bike that you select for 90% of the riding you do—this is the essence of Ronin as a tool.

If you’re searching for a versatile bike for everyday use, extended day rides on mixed surfaces, or multi-day tours, Ronin has you covered. This is a bike that can easily adapt to your lifestyle, serving as a capable tool and reliable companion. The frame is convertible between 700c and 650b, accommodating tires up to 43mm with 700c wheels and up to 55mm (2.1 inches) with 650b (27.5”) wheels.

As a true mixed-terrain, modern adventure bike, Ronin can take you confidently to the destinations you’ve been charting in your mind. It’s a worthy selection to become a trusted companion for memorable adventures, and seeking contentment through a dynamic life lived through your cycling experiences.
