Soooooo, I purchased a Fizik Antares 00 saddle for the second time in my life, and for the second time, it has shredded the underside of my bib shorts. The same thing happened a few years ago, but I put it down to the material on top of the saddle, and didn't really look any further in to it than that (and simply replaced the saddle). This time though, the material on top of the saddle is slightly different, so I started looking in to a bit more. From what I can see, it's actually the carbon material over the rails that's causing the issue. To prove this, I have put electrical tape over the matieral, and this does seem to have resolved the issue. I emailed Fizik about it, and they didn't really understand what I was talking about, simply saying, if I wanted to return the saddle for a warranty claim, I could go ahead and do that (which I really can't be arsed to do). Pretty poor.
Both times Wiggle have kindly replaced my bib shorts F.O.C, so big props to them for good customer service.
I've read some older posts online, so this done not appear to be an isolated issue.
I am wondering if anyone has any thought? I am not a particularly big rider, 67kg, I ride mostly centre of the saddle, occasionally pushing forward for efforts, and right back when on drops. I don't move around a huge amount though. I'm keen to get to the bottom of it (excuse the pun) as it's always a worry that I'll ruin another pair of bib shorts.
