I too suffer from wrist pain when I ride (I have carpal tunnel). I started seeing a chiropractor and it really did help - I'm, for the most part, pain free these days. He gave me a series of exercises to do a couple days each day and they really did help along with his adjustments.

I also purchased a recumbent and though I do not ride it a lot it does give my hands/wrist a much deserved break a couple times a week.

Keep us posted.
