OakLeaf : Fantastic questions that I really should have answered from the start.

I am a racer, or at least getting back to training after an extended time off due to an injury, so aero or at least not upright is pretty important.

I have fewer issues in a more upright position but it's still not terribly comfortable.

I went out for a ride yesterday and played around with that lower-back flexibility and where/how I sit. What I learned :
  • I'm pretty sure I need a cut out or channel
  • When I get more aero with my current saddle I get WAY too much pressure where it shouldn't be
  • If I shift back in this more aero position it alleviates most of those issues

My current saddle has a cutout, it's pretty tiny and in the middle of the saddle. What I'm pretty sure I need is a larger cutout or channel that extends through the nose of the saddle so that all the pressure isn't on soft tissue when I go aero.

That is why I was looking at Fizik (the arione donna).

I'm going to be off the bike again for two weeks or so for a silent meditation retreat. I'm not going to be able to try anything before leaving but I want to gather information so that I am ready to go when I get back.

I've read about saddle shape, pear vs T, and some of the important points but I still don't really understand anything about it.

M-Rad : I am pretty sure that riding more aero will always create a different weight distribution between soft tissue/sit bones
