I experience this exact type of pain. The best way I can describe it is a bone bruise all along my sitbone area. I don't experience any discomfort while riding, the pain sets in about an hour after my ride is over. I'm a beginner cyclist. I purchased a Specialized Dolce from my LBS a few weeks ago. I've only ridden it four times for approximately 30 minutes each time, wearing what I lovelingly call my diaper shorts. After my first ride, my girly bits were none to pleased with my saddle. I realized that the saddle was positioned too far back and I wasn't carrying my weight on my bum, but on my inner thigh region instead. I moved it forward an inch and voila! My girly bits are happy and now my sitbones are angry. I've experienced the post-ride sitbone pain with no improvement for the past three rides. I expect there is an adjustment period, but seriously, how long does it last? I have to wait four days or so in between each ride for the bruising to subside. This is really dampening my spirits on riding. What is a typical adjustment period for a beginner? When do you decide it's the saddle, not your bum, that's the source of the problem?
