I'm looking to buy an inexpensive 9 or 10-speed road bike in size 56 or 55 (aluminum preferred) to be used indoors on a trainer.  Chipped paint?  No problem.  You want to keep your wheels?  No problem.  It fell off your roof rack on the highway while you were doing 70 mph?  Mmm...we can talk!  Please respond to:      Thank you.
