resembles a Fi'zi:k Aliante Carbon. I had the regular version of said saddle and it's nice...just not to my particular liking compared to a flat saddle.
Ovalized rails aren't a defect. Many carbon-railed saddles are shaped as so for what I assume is a means of strengthening. I have Trigon VCS03 full carbon saddle, and it's perhaps of a small selection of saddles that have regular-sized carbon-rails. I'm 140lb, so I can't really speak on whether the lack of ovalized rails is a bad thing in reality.
