Just a followup -
Yesterday I went to the Peter White web site that MichaelW recommended. It has some excellent advice about adjusting you bike to fit you, with an explanation of the trade-offs (comfort vs. power, aerodynamics vs. enjoying the scenery). Probably the best thing I did was adjust the seat back as far as it would go. This took a lot of the strain off my hands, and I'm leaning a little more foward so I'm slightly more aerodynamic. It's amazing what a couple of inches will do (insert rude comment here...).

Combining that with adjusting the pre-load on the shock mounted seat to "fully loaded" - i.e. no spring to it- and tweaking the handlebar and wow! What a difference. I've added probably 3 mph to my average speed, can power up hills better, and am less fatigued. Rode 25 miles yesterday running errands, etc, and another 15 miles today with Mrs. HogWild, and I feel great.

Thanks for all the advice, and be sure and check out the Peter White site if you feel like you could use an adjustment. As Michael said earlier, it's at http://www.peterwhitecycles.com
