I'm 6'0" and 245 lbs, and I'm wondering if I'm going to hurt a couple of '87 Schwinns with Columbus Tenax tubing? They're both bone stock, the Super Sport with Rigida SX-100 700x25c alloy rims and the Prelude with Weinmann 913S 700x25 alloy rims. The rear on the Prelude is already out of true about 1/4" both ways and a few of the retainers around the spoke nipples are popped out. I bought it this way. The Super Sport is in the mail, so I haven't seen it yet..
I've got a guy coming over tomorrow to possibly buy my '77 Le Tour II, and I'm wondering if I should keep it and ride it until I get down to a reasonable weight before hopping on either of the Columbus Tenax Schwinns with their skinny alloy rims? And if so, what would be a reasonable weight to not damage either of them?
And yes, I know, people are gonna wanna see pics, so they're attached.
