25mm road bike on the TransAm?
I am planning to ride half of the TransAmerica (West to East) next summer, with my 13 year old son. I have a touring bike that I have taken on one delightful 500 mile tour, but am having a hard time finding a suitable bike for him (about 5 feet flat in height).
Is it a reasonable plan for him to do the tour on an unloaded road bike (he has a Fuji Newest 3.0 road bike that fits him with 25mm tires)? Or should I keep hunting for a budget xs touring-specific bike, perhaps on Craigslist? My plan is to carry his load on my front panniers, as he is pretty small and we are doing a credit card tour, so there is no camping gear.
