Japan’s SimWorks just shared news of a refreshed version of their Doppo All Terrain Bike (ATB) frameset, which was co-developed with Shin Hattori of Shin Fabrication, and is what they’ve positioned as their interpretation of a “Swiss-Army solution for the free spirited all-road rider.”
With a name roughly translating to “going alone,” the Doppo was designed with wandering cyclists in mind, and it offers a suite of features geared toward long, loaded rides away from roads, including clearance for 700c x 43mm or 650B x 55mm tires, mounts under the downtube and on the fork legs, provisions for racks and fenders, and a Tange CrMo steel frameset built with tried and true specs such as a 27.2 seatpost diameter, 68mm threaded bottom bracket, and 1-1/8″ head tube.
SimWorks Doppo ATB Features:
- TIG-welded Tange CrMo Steel Tubeset
- Tange Original Multipurpose Fork
- 142mm x 12mm Paragon Machine Works dropouts
- 160mm max disc rotor
- Flat Mount front and rear disc mount
- 1-1/8″ head tube
- 27.2 seatpost tube
- 68mm standard BSA threaded BB
- Max tire clearance 700c x 43mm / 650b x 55mm
- “Three-Pack” Mount under the down tube
- Fender and rack mounts
- Includes front & rear thru-axles
- Small Batch hand-built in Japan
The SimWorks Doppo ATB frameset is available in a new sandy beige color and five sizes, from small to extra-extra-large. It’s priced at $1,999 for the frame and fork without headset or seatpost clamp. Note that frames ship from Japan and buyers are responsible for any local customs/duties.
