I am new to this roadie stuff, about two months, and on one out of three rides I experience lots of lower back pain. The pain is located between the bottomn of my rib cage, and the top of my hips, and it doesn't have a pattern as to its occurance. I have been messing with my seatpost height trying to solve this problem. My question is should I raise or lower it? I ask because the pain only occurs after about ten miles of riding, and I don't ride that often, and I do not have the time to ride ten miles after every adjustment. Thanks

The answer is probably lower it. But the best answer of all is to cough up the dough for a professional fit... evaluating not only seat height but also fore-and-aft, as well as stem length. All can cause varying aches and pains if not fitted right. Even crank arm length can be a factor if your legs are particularly long or short.

Most really good roadie shops can want upwards of $100 for a good hour-long professional fit session, but some will then cut you a deal on any components you need to swap. Other shops offer sort of the speeded up version of a fit for $40 or so. Just do it!!!!

Are you pushing big gears? If you are pushing bigger gears than you are use to, you may begin employing your lower back muscles more to push those gears. That said, I do agree wholeheartedly with jtolleson that you have to start with a proper fit. You may want to try a do it yourself fit method before shelling out the dough. Just about any cycling book dedicated to training will have a discussion on things like determining frame size, seat height etc. I believe Colorado Cyclist's website has a lengthy discussion on bike fit too.

Bike set-up and high gears are not the cause of cycling related
lower back pain. High gears only magnify the fault of the normal
pedaling style which hinges all the strain in the mid/lower back area.
Incorrect bike set-up can cause discomfort but one can compensate for
for a faulty set-up. With the correct pedaling technique, you can
hinge all the strain in the hips and the higher the gear you use, the
more relaxing it will feel in the lower back area. That pain after
ten miles is caused by the continuous strain which you are putting on
your lower back and your lower back is not 100% perfect and is being
aggravated by the strain. If I am correct, that pain should get
worse as you continue to ride and stops as soon as you get off your bicycle.
