I was wondering if anyone had any information about the 1969 Schwinn Super Sport? I just got what appears to be a SS manufactured in July 1969, but some details don’t match up with the info posted on Mark Rother’s article on Sheldon Brown’s site.
The serial number on the bike pictured (a recent craigslist find) begins with GE (according to Rother: July 1969), and the joint between the downtube, top tube and head tube looks rounded in the classic fillet brazed fashion. But (and this is where I’m confused) the seat-, down-, and top-tube junction does not look fillet brazed. These tubes also seem skinnier than the article suggests they should be. The serial number is on the dropout though Rother says that after 1965 they moved to the head tube.
Everything else matches up – the serial number, color (“campus green”), chrome fork, original components (brooks saddle, Ashtabula crank, stem shifters) etc. all seem right for the ‘69 super sport.
Obviously I’ve significantly altered its stock configuration to set it up as a fixed gear with sealed cartridge bottom bracket (using the Truvativ American one piece conversion cups) and sugino cranks, but I still have all the original bits in a box if any of them would help.
My guess is that (though Rother’s article doesn’t mention this) in 1969 they were using some mix of welding techniques on these frames. Anyone know anything about the materials used or the frame construction?
Thanks for your help!
