The one with the plastic, rather than carbon shell.

There seems to be an issue or perhaps a manufacturing defect with the plastic shells, perhaps that manifests in cold weather. Each of the last two weeks, I have broken one of these saddles in precisely the same manner. I was on my gravel bike climbing a relatively significant grade, and the temperature was just above freezing. Both saddles snapped at the nose.

The saddles were Fizik Antares Evo Adaptive R1 saddles, both of which were purchased last season. They felt great, and I really like the shape and the 3-D printed surface. But the plastic shell appears to be an issue.

Both days I ended up rolling back to the Start/Finish alternating between standing and sitting on the naked rails of the saddle, which remained fixed to my seat post.

Fizik is refunding my purchase price on the saddle I broke last week. We’ll see what it does with the second one.
