OK, I recently got an ebay find of very nice CCM frame with odd dimensions (52cm seat tube, 56cm top tube) that match exactly what my FIT specs are for an ideal bike. I'm getting it to primarily see what a custom built bike would feel like. It's only the frame and fork, and the link is here: http://cgi.ebay.com/ws/eBayISAPI.dll...m=150197243902

I also got a Schwinn Peleton, 1983, with only one season of riding on it for a great price. It has the original components on it (Suntour Superbe) and has been hanging in a garage since 1985. The owner got into racing and bought a different bike. It is a 52cm bike and the top tube is 53.5 cm.

I am wondering what to do here... I really want to try out the CCM. I was going to coldset the rear and put the 105 components on it from my Klein, which I don't like. But now that I have these Suntour components, I kinda want to use those.

On the other hand, the Peleton is a pretty cool find to keep original, but it's way smaller than any bike I've ridden. I usually have to ride 58 cm bikes to get the reach comfortable, and the top tube almost touches me with shoes on. I think I can get something to add 2.5cm to the reach, but will that affect the handling too much? It only weighs 20 lbs...and it's a much nicer bike than the CCM.

What would you do?
