I just tried one last night. I measured exactly in between the small (140) and medium (150) sizes. I tried the 140 to make sure it wouldn't love it, but it felt too small (not too surprised since the saddles I've been most comfy on are at least 150mm). So, I did 25 miles on the 150.
The good:
  • It's got a stiffer base than the Ruby that I've been on for a couple of months, which I like.
  • The "dent" rather than cutout thing is pretty sweet. Even with the squishy padding, my soft tissue was very comfortable riding on both the hoods and the drops.
  • That "bump" of padding in the front was also really nice when I was doing some hard pedaling in the drops, where I tend to rotate forward towards my pubic bone (not comfortable at all on the Ruby).


The not-so-good:
It's got pretty squishy padding that started to chafe my side-taint about halfway through the ride (similar to what I've experienced with a Terry Butterfly and the SI Shiver).

I'm going to try again today with some Assos creme, but chafing in that spot has been the downfall of many saddles before this one...
