I've ridden mtn bikes for a while and want to PU a road bike for a change of scenery and conditioning. (Ride from the driveway). It's just me, but I want a great bike so I won't be tempeted by UGI and because I like good equipment. Trying to choose between these bikes right now: Klein Q Pro / Litespeed Tuscany / Airborne Zepplin and a Ind. Fab crown Jewell. All have upscale components and carbon forks. My riding will be just for fun with a couple 50K charity rides a year thrown in. What would you leather crotched "old timers" recommend? Oh yeah, and I'm older than dirt, with the attendant "back" issues.
