Doppo translates to “going alone.” On display at the Sim Works Pop-Up at the Cub House was the steel version of their Doppo ATB bike or all-terrain bicycle. We saw the aluminum version from the Chris King Swarm coverage, and we’ve seen this steel model in Japan being manned by Makoto during our Mount Fuji tour.

These frames are made by a builder in Nagoya named Shin Hattori, exclusively for Sim Works, and for the first time, they’re now available in the USA through Sim Works. They feature a number of braze-ons for racks and fenders, as well as a Tange fork with a unique fender mount. This particular model was built up with chubby 650b road tires and fenders.

The Doppo comes in size Small through XXL and will fit a 43mm tire on 700c or 2.1″ on 27.5″ wheels. A frameset retails for $1,680 shipped from Japan via FedEx. Head to Sim Works to see more!
