Saddle, shorts or lube?

[KnottedYet]

Someone asked my outside-to-outside ischial tuberosity span?

I don't know...I don't have any pain in my sit bones. They feel supported and so I'm guessing that is pretty good fit. I did catch myself scooting back on the seat to ease the pressure on the front.

You wouldn't have pain in your sit bones from a poor saddle fit.
You would have pain in your vulvar area.

If you are scooting back to ease pressure off the front of your crotch, something about your saddle is wrong.

If you sit on a kitchen chair, does your vulva hurt after 20 minutes? Do you have burning pain sitting on a kitchen chair? When you stand up from a kitchen chair, does your crotch continue to hurt for hours?

No? That's because when you sit on a hard chair your weight is on your sit bones. A bike saddle that fits and is set up right should be no more uncomfortable than a hard kitchen chair. Your weight should be on the bones, just like it always is (they are tough).

Don't be frightened of measuring your own pelvis. It's easy.

After you get your measurements, check the cut-out test.

Terry Liberator shouldn't make you numb after 5 miles. No saddle should make you numb. The Terry doesn't fit you either. Either it's too narrow, or it's too pear shaped and you scooted forward on the Terry just like you did on the Bontrager. Terrys are notorious for being pear-shaped. (They are also sometimes over-padded, which can cause problems as well.)
