Thanks for the advice RR! I would be completely happy with a used TT bike too, but cobbling one together is a great idea. Only 2.3 more weeks in the cast, then back to training for the America by Bicycle trip. I'll definitely report back to TE'ers on the trip - I hear that the Wyoming leg has lots of wildlife and natural beauty. I get a fiberglass cast this Weds - should be better than this clammy plaster one! Tokie
