Retro Kona Cinder Cone Bike Frame. 1993 Model with double butted steel tubeset; to my mind the best year for retro Kona’s. It was the first year to get serious about weight saving and had the nicest two colour fade paint jobs. This was the same frame as on the Lava Dome (the cinder cone was specced and priced higher). Signs of the years and age. Rusty in places but structurally sound. No cracks or dents.
