Hi Summer, I know what you mean by the tailbone pain when you get off the saddle. I've experienced that too so I can sympathize.

Finding a saddle with a proper fit and design will help your tailbone pain. Specialized has a tool to measure the distance between your sitbones so that you can get the right width in your saddle. Believe it or not, the tool is called an a$$meter and you sit on it and the dealer measures the distance between the impressions made by your sitbones. Specialized offers some of their saddles in 3 widths. I have one that has a pretty significant cutout for the tailbone. I don't have the soreness like I did with my Terry saddle.

If you want to try and measure your sitbones yourself, here's what worked for me. Lay on your back with your knees bent and feel for the sit bones. It may be helpful to bring your knees to your chest. Take a tape measurer and measure the distance from the outside of each sitbone. My sit bones measured 5 1/4 inches, which is 130 mm. Specialized recommends that you go with a saddle one size larger than your measurement so that you can have some room for play as you change positions in the saddle. So in my case, I would choose a 143 mm saddle, which is the most popular size.
