Does anyone use "upright" bikes for light training or mid distance riding?
I have a continual shoulder problem that is getting in the way of longer rides on the drop bar bikes (either in the drops, hoods, etc). Moving around on the saddle works for a while, but eventually there is a very sharp and present pain while riding that must be endured. Sometimes are better than others, but it's become clear that this doesn't happen on my relatively upright mountain bike. Yes, it sucks that my upper body gives out before my legs do, thus the frustration and intent to have a plan for those times.
Thinking of a bike that could be used for 30 mile or longer rides in relative comfort. Not looking for speed, obviously, with the riding position. However, I'm thinking a 15-16 mph clip should be possible and sustainable in all but windy conditions.
What are the considerations for doing this, as compared to a drop bar bike (frame size, saddles, crank length, pedals, tire size)? I'd like to do it right in terms of the right combo for spirited riding (though both looks and performance would be nice).
