Pain around the right wrist and shoulder area could translate to poor saddle positioning. If the nose is too low, then your body will slide forward, placing greater stress on the wrist and arm. Also try adjusting the fore and aft of the saddle by 1/4" each time.

Ride with no hands. Is your butt firmly planted at the widest area of the saddle? If you noticed that the body is sliding forward as you pedal, raise the nose by 1/8" and retest.
