Fizik Arione CX K:ium Saddle
The Arione CX features a new lightweight foam yielding a 20 gram weight reduction from the standard Arione. This saddle features Fizik's own Spine Concept technology - which realizes that cyclists have varying degrees of flexibility and human flexibility affects riding behavior when cycling in a high performance position.
So, I'm a smaller guy, 5'5 150 ish, and have the 132mm version of this saddle. I actually moved it from my racing bike to my commuter (c-dale caad x) because it was so comfortable. It just fits my sitting bones well and suspect the case will not be the same for larger boned people. It is well made, the kium rails help smooth out the ride, i like it. the only reason it got 4 stars is because of the price, Fizik seems to be standard deviation above similar quality products price wise. I would absolutely buy this saddle again though.
This came on a new bike and is light and very well made but it doesn't fit my butt. More specifically, it is too straight and doesn't sag or curve at all in the middle so it doesn't feel comfortable. As with all saddles, one (wo)man's pain in the butt is another (wo)man's comfort zone.
