The new SimWorks Doppo MTB frameset is made of chromoly steel, has plenty of mounts, and can clear 27.5 x 2.8″ tires. Find photos and more details about the Japanese brand’s latest bike here…

The SimWorks Doppo MTB is the latest addition to their line of made-in-Japan chromoly steel framesets, rounding out the brand’s small and quirky line of bikes and featuring the latest mountain bike standards and clearance for big tires. The frames are produced in small batches by Shin Hattori, an accomplished builder based in Aichi prefecture, and are hand finished for tight tolerances. The SimWorks Doppo MTB is made from Tange Chromoly Steel tubing and can be setup rigid with the included steel fork or with your favourite 120mm travel suspension fork. At first glance, the geometry looks like it could make a great all-rounder for a mix of mountain biking and multi-day bikepacking, leaning towards the comfortable and stable side of an all-road touring bike.
