I recently switched from a Trek 7100, to a Trek 7.5FX bike.
After riding for a few weeks, I have noticed that around 8-10 miles into a ride, I start to get quite sore in my right shoulder. It's isolated to that area only, and usually goes away right after I stop riding.
I rode the BaCoon ride in Waukee, IA over the weekend (76.6 miles) and my shoulder is absolutely killing me now.
Is this possibly a fit issue? I fitted myself on my Trek 7100. I rode it very tall, with my seat high, handlebars back so I wasn't leaning forward much at all, etc....it was a 20" frame.
The 7.5fx is a bit more of a forward lean, is a 56cm frame, I added bar ends, and then moved them closer to me after a few weeks, thinking maybe they were too far forward.
Any suggestions? Should I got to a local shop and get fitted onto the bike?
I have attached both pictures of the 7.5fx (red in color) and the old 7100 I used to rider (black and silver)
