Need Some advice...
So I've been at this whole thing for awhile now trying to get just one bike good and running but it seems like I can't really ever pull anything off completely right. Bough a 63cm Nishiki off craigslist then realized 3 things, 1) A little too big for me, I'm 6'3 but i didnt really have nad safety room and feet kinda got close to liftoff a few times when pedalling 2) Seatpost was ridiculously stuck, tried every damn way to get it lose, torquing it, pipe wrenches, etc. even freezing it so the (aluminum) post would shrink faster than the tube, didnt work and made the sizing problem even harder. 3) Found out after buying it had 24" wheels on it, and wouldn't fit 27's because of the placement of the rear brake cross bar, was a real tight fit on the front fork definitely too. So, I sold that off craigslist to some huge hipster guys as a weak singlespeed.
Second bike, friend found an old bridgestone with steel cage pedals n leather straps layng in a bush, we took it, tore it apart, found out that under all the rusty cr*p it had vertical dropouts, he was convinced I could make it work, I took it and thought I could at least use the stem, handlebars, pedals, and whatever else I could find when I bought another.
Third Bike, got talked into buying a Schwinn Varsity for super cheap after not nearly doing enough research. Stripped it all down, bought new cranks, wheelset, chain, and a converter to fit that damn humongous bottom bracket. Realized cant swap out the stem or the seat post because of it being smaller tubing. Can't change out the seat either because of instead of using a tubular clamp set up like standard, its got little vertical rails so I'm stuck with a whacked out seat. And, it weighs a million pounds so its a freaking tank. its a 58cm but it feels small for me. 6'3 and a 34" inseam.
After telling my friend about all this he tells me his neighbor gave him a Motobecane Le Champion frame with a carbon fork for free, worth like $800 for just the frame. It was kinda dejecting although he has one sick ass set up.
Now for the advice, I realized I'm looking at selling the bikes and moving on to another, but after this many mishaps with conversions I'm starting to think of just buying a new frame and some components and swapping out what I already have, then selling both old frames as stock, I still have all their parts. Started looking seriously now at the IRO Mark V, but still I'm unsure. Kinda starting to think that after all these problems I might just need to stay away. Any insight would be greatly appreciated. Really frustrated and needed to let it out to people who know bikes.
