I live for the CABE
Its not so confusing for those with a few of the bikes with these rims/tires.Wait, what?! That is confusing. I dont think anything was stamped S7 here, or did I miss something?
Assuming this is something even semi-normal and located in the US...
A 26" (not 27) lightweight tire from the 70s, or the bike boom, or back a few years from that has to be one of the two right? 590 as seen on UK 3 speeds and US department store lightweights or 597 Schwinn?
This is why we should NEVER be using inch sizes anymore. It's a mess. It's not the inches vs Metric, it is all the contradictions and if-and-but-or's in the old system.
Hey @Relic Racing, If this bike has any tires on it, please post pics of the markings, or post the markings. If there are inch markings, post. If there are metric markings, post, if there is S-anything or E.A.-anything post that too. I swear we can make sense of this, and probably quickly.
Like they did with most things American in the 60's-70's, the Japanese, this time ARAYA, knocked off the Schwinn Special sizes also. I have seen ARAYA Schwinn sized rims before. I wouldn't be surprised to see an S5/S6 Schwinn sized rim (597).
A person could just measure the rim diameter.....
I would have already posted the Rim OD differences but I've put my 26" tire bikes away in prep for me going traveling in a couple weeks.
