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.
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.
