I would like to convert a bike to a tourer and I have access to a load of frames.
I've seen people saying that mountain bikes convert well to tourers and haven't heard much on road bikes. This is confusing because road bike geometry looks waaaay closer to touring bikes.
My gut instinct is to convert a road bike since the geometry looks closer. What is better to convert?
Edit: My route is the west cost of the USA from Vancouver to San Diego. I am going to be fully loaded, a.k.a. fully self sufficient but I am investing in lighter gear.
