That looks awesome
mikeschn . I was finally able to dig my Schwinn Heavy Duti out of the garage this weekend for a quick wash and pictures.
This was put together in the early '80's which is why the colored alloy components were so available. I also had a fluted red alloy seat post that I replaced.
I worked at a Schwinn dealership at the time and was able to order the decals from Schwinn.
I believe that the Heavy Duti had a wider rear triangle that could fit 2.125" tires that the middle weight Typhoons and all could not. Please let us know if this is not correct. By the way, these are Schwinn Typhoon Cord tires ordered from Schwinn at the time I built this bike up. They are showing their age.
The rack is a Schwinn branded version of a Blackburn style rack anodized red. I don't know how long they were available for.
