America By Bicycle is a fully supported tour. Mike Munk is their tour leader and I have read his advise. The reason for using this forum is to double check since I feel that I have much riding on this trip.
Therefore I am very grateful for your comments.
I could use the Trek Hybrid except for the weight of 32 lb.
I am looking at a Specialize Road bike (Not a Touring Bike)
I am told that this trip is bad news for Wheels and Tires. Mike recommends size 28 to 38 with Kevlar and rubber side walls.
He also recommends Gears of 39/28 or 39/32.
Aero Bars are supposed to be good.
I am now training intensely and finding that my focus changed from my rear end to my legs. Therefore I am less sure of the need for a Sprung Brooks saddle.
Sorry for this long message but I am thankful for your interest.
