Awhile ago I am quite certain that I saw these Seat Post pumps branded "Zorin Biologic" were made for regular bikes. I thought it was interesting but I didn't need another pump at the time. Now I want to get one, but I spent some time searching and all I find are parts that are apparently made by or at least for Dahon. I'm not certain if these will work on non-Dahons, and non-folders for that matter. Can anyone help me out here? I'd love to get something like this for one of my bikes but don't want to get something that won't work. One bike is a 1982 Trek 613 and the other is a Swobo Dixon. I'd prefer to put one on the Trek but I'll take one for the Swobo instead if that's the only option.
