If you want something for the road that is actually faster than a road bike and way more comfortable, do some research on the lowracer style recumbents. You won't have any issues whatsoever with wrist, back, or bottom end pain. 100 mile rides and no pain plus you get from point A to B a little quicker.
here are some pictures of some lowracers.

Don Smith is not a very fast rider on a road bike........ has done a century in 6 hours on his road bike and that was the best he could do solo. Same course with the lowracer and he did it in 4 hours 30 minutes...........no drafting.
