Bad pain in my right shoulder...

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)

One HUGE difference I noticed, looking at my 7.5FX and pics of my 7100, is the handle bar stem length difference. The 7100 just cam straight up wit han almost 45 degree angle to the handlebars.

The 7.5FX has a 120mm Bontrager stem on it, with 7 deg angle. Would trying a shorter stem possibly take care of my problem? I am seeing any where from 90mm - 110mm as shorter options.

A shorter stem would be an easy thing to try. When you get comfortable, be sure and measure the distance from the saddle to the bars and write it down for future use.

Keep in mind that there may be some other issue like a conditioning problem, and old injury, arthritis or poor riding position.

Also, riding long distance on flat bars can be a problem - limited hand positions.

You probably need to have somebody with experience look at your position and riding style. They might be able to help with fit or riding advice.

Do you do any conditioning in preparation for riding? If you don't you should probably look into that, also. It may help alot.
