I really like the overall comfort and fit of these bibs. (size large, 6'3", 170lb). I've ridden them 3 times on an indoor trainer for 60 minute rides. The one thing that I've noticed is that the chamois is somewhat thicker than my other bibs, and it's not positioned exactly over / under my sit bones, then it just feels a little odd to me. And the chamois is pretty big, so I feel like it's a little more difficult to get it in exactly the right place.
To be fair, more padding is probably better than less padding, and I probably need to give them a few more rides to break in. So, even as they are now, they're good for the 45-60 minute rides. But I think they need a little more bedding in before I'd try them on a 2-3 hour ride.
