Thanks everyone for the tips and links. I read a bunch more about it (there's way to much folder info to ever read). Invisible correctly guessed/identified what I'm after. Reasonable budget, higher top speed, lighter weight, conventional drive train. I could start with a used Pocket Rocket (56cm) and go from there. I've been looking to see what pocket rockets are out there. What's a guess at the bike weight in basic road race form without crazy spending? I'll read up on Capreo cassettes compared to 10 or 11 sp conventional.
