I am a female. I am now starting to ride much longer miles. My last ride was 70 miles with around 6000' elevation. I am so sore! For one thing my chamois stitching was on my sit bones for a while causing severe bruising. So I am getting new shorts with no stitching. But after researching my main problem seems to be the pelvic ramus area (or the area between the sit bones). I have deep bone pains.

I am currently using the Selle Italia Diva Gel Flow. I have just had this saddle for a few months. I think it isn't right for me. I do have wide sit bones. And I like the cutout. Maybe I need a firmer saddle?
I tend to ride in a more aggressive position. I seem to move forward on the seat to get extra room between my seat and my (um) leg/pelvic area. Kinda like I need a narrower seat.

Any suggestions?
