Just wanted to post a hello before diving in. I'm into Schwinn lightweights and Stingrays myself. Have three complete Stingrays ('66, '67 and '68), a fourth project ('68), a '71 Manta Ray, a '74 Sprint and a '72 Sports Tourer on the way, courtesy of this forum. All of 'em are riders, between me and my nephews.
To paraphrase Ben Franklin, I believe, it's better to be thought a fool than to post and remove all doubt. I've got a lot of bikes but not a lot of knowledge, so I'll spend more time reading than posting, but I do look forward to hanging out.
