The only oddball part is the expansion seat post, but Peugeot also used those for a short time. The original was heavy stainless, so I modified an aluminum post to fit. The bike is heavy at 24 pounds. The stays and fork are high tensile steel. That's why selling them to boaters didn't work. "Uniqueness" is the only reason I own it. I get questions about it every place I take it. It drew a small crowd the last time I took it to a bike swap. I paid $25 for the frame and fork.
