Someone was asking about a replacement chainwheel on an older bike they had so I pulled out a few to give them an idea of what was out there and different mounting styles. They were specifically looking for a decorative design appropriate to the bike's time period (they never stated year or brand, nor provided any photos) with 48T. Unfortunately, without the specifics I was shooting blind but offered some images as examples which range from the 1930-1970ish. Some thread directly onto the crank, some are swaged, and some are bolted (3-5 bolts). I think that once the weight of parts became more important with aluminum cogs for racing bikes, the decorative theme was abandoned to shed some weight even extending to factory "drillium" rings, and also rings that were being extensively engraved and/or cut-out both providing decoration and weight reduction. As shown, most early chainrings proudly displayed the bike's brand or logo (e.g. Raleigh "Heron", Rudge "Hand", et al.), but there were also many early parts manufacturers making chainwheels with artistic designs (e.g. Fonlupt, Solida, et al.). I would love to see more bike/parts manufacturers having a flare for more ornamentation which would provide more name recognition and advertising, as well as making a bike look cool, but without affecting function or weight. I'll forego the return of top tube tanks, fins, and other ornamentation that wasn't part of making the bike functional other than maybe having a (nearly useless) light on it.
Here are but a few that I have taken from frames, are still mounted, have as decoration in my shop (but possible future use), or are awaiting for installation. Please pardon some old (repeat) photos from my other posts.
