Yes, they sold a derailleur equipped city bicycle but if you've got Dia-Compe levers, you can almost quarantee that they're replacements, along with those handlebars and presumibly a mattress saddle. However, the clincher is whether it has or had a front derailleur. The city bicycle was only a 5 speed.

I don't recall these bicycle in orange. I do remember white, brown, blue and a lime green. They didn't have a model name on them. We used to go by the model number on the shipping cartons. If I recall correctly, it was a model 110.
