I was looking at the latest America by Bicycle tour brochure, and in it they recommend buying a new bike before taking a tour. I have four road bikes, ranging from 10-25 years old, all expertly maintained by my LBS. What's wrong with taking an old bike you know well? I was looking at the Fast America South 2,899 mile coast to coast in 27 days. It says you have to be able to average 16.5 mph, so this leaves me out. I couldn't average 16.5 off a 1,000 foot cliff! Maybe they have a Slow America South tour for old farts on old bikes.
