Lately I've been getting a pain in my left sit bone after about an hour on the bike. It feels as if a ball point pen is being jabbed into my buttock. This has to be a saddle position problem, right?

I've been riding for a long time, and tend to get my fit just where I want it, but sometimes things happen, saddles get replaced, and I seem to be back to square one. Frustrating, sometimes.

Say, has anybody seen my pen? I left it around here somewhere.

Sit bone pain is generally the result of riding too upright and having your pelvis rotated too rearward. Try the drill I described in the current back pain thread. If one rotates their pelvis forward which straightens the lumbar when riding in the drops...your sitbones rotate more off the saddle naturally as the front of the pelvis becomes more loaded...in some instance too much so in fact causing pain on the perineum. So its a balance of pressure each of us seek.

In my experience both sit bone pain and even saddle width are affected by pelvis position. As a visual if you ride a road bike like driving a riding lawnmower, then you better have a very wide and plush seat more like a tractor as a typical road bike seat will place too much localized pressure on the sitbones.

I've been experimenting with the pelvis foward position and my sit bones come clear off the saddle. Next ride I'm going to move the saddle back ever so slightly. Is it expected that the sit bones comes off the saddle? I thought not, just that a more narrow saddle may be needed?

I feel like I generally do rotate my hips forward a fair amount, but I probably unconsciously let them fall back to a more upright position than I should. I'll have to experiment with this to see if position is indeed the culprit. Thanks.

Also, if it is one side only, check your saddle nose angle (left to right) to see if it is straight. Also check your cleat position to see if your left foot cleat is set farther back than the right. You may also be favoring your left leg and pushing that hamstring more. You may want to move the saddle a tad forward as well.
