I briefly owned an SR Semi-Pro. Came outfitted with Shimano 600 Arabesque components. I can't recall if it had any indication of the steel type. I ended up selling it as I had too many other projects going on at the time. The ride wasn't notably bad or good. Seemed like a solid bike. I recently had the opportunity to pick up a second Semi-pro thinking perhaps I would abscond with the 600 groupset for another project. Seller was asking a $140. It might have been the ugliest paint scheme I have ever seen. It was a drab tan and brown. It was pretty awful looking. Fortunately for my case of N+1, the seller also had something much shinier that was well worth the visit, so the SR stayed behind. Anyway, that pretty much sums up my brief experiences with SR bicycles (both Semi-Pro models). Not sure that helps a whole lot.
