As I've done for years, when ever I see an older or small bike shop while I'm traveling I tend to stop and have a look. I stopped at one on a trip to FL last week and got to talking with the guy about old bikes after seeing he had a few hanging in the shop on display. Conversation turned into a tour of his parts area where I noticed a pair of super wide Araya steel rims, marked 27"x1 1/4"x1 3/8" W/O. I've seen old Araya steel rims, most marked w/o for what ever reason but never a set that are as wide as most middle weight rims?
When I asked about them, he had no clue as to what they came from, I pulled them down to take a closer look just out of curiousity and he said if I wanted them, to take them, "They've been hanging there for 30 years now". So I came home with a pair of new old stock steel wheels, really wide steel wheels. Now, what would have taken these rims? Obviously it wasn't high end, but my guess is that had to have a pretty stout tire on it? Even a wide 1 1/4" tire would look lost on these. They take a normal bead diameter, I did inflate a 27x1 1/4" tire on one, but the sidewalls are angled outward toward the rim edges. These rims look as wide as the S-7 rims on my Schwinn Typhoon. The hubs are steel as well, and made by Sunshine with medium flanges. Both are nutted hubs.
