OEM Bontrager saddles are not known for comfort.
^^^This
My Bontrager Race saddle on my old Trek 2.3 was awful. I didn't get any numbness, but soreness during and after the ride was common.
The Fizik Arione on my R3 is nice (I like the flat surface and there aren't any pressure points), but I don't think it's wide enough for my sit bones to be on that sweet spot of the saddle. My sit bones feel like they are right on the outer edge of the saddle, so there is some slight discomfort if I stay seated for a long time. I tend to get out of the saddle a lot so it's not that big of a deal, but I'm still looking for a replacement saddle.
I'm thinking about the Fizik Antares since it's a bit wider like the Aliante, but more flat like the Arione.
