No! The truly dense don't think to ask the question....
This thread has gone a little off track as it's onto a track about saddlebags because they offer a way to get around the lack of eyelets on most carbon bikes. maybe people could add comments about bikepacking bags and CF bikes they might like for touring. I like Carradice saddlebags, but there are other luggage options to pair with a CF bike
I'm a Carradice fan too, I've done a fair bit of cc touring with a Nelson longflap (even a Pendle for a weekend trip) on a sub-20lb roadbike. Not carbon, but really that's immaterial, and ironically it has a cf seatpost. But I've never been a huge fan of the bagman, and for some reason the trick with the buckles has never occured to me.
If I were the OP I wouldn't be messing about with racks on a cf frame. I'd either be going ultralight with a saddlebag and/or frame bag, or I'd be getting light steel tourer for going fully loaded. There comes a point when compromise becomes a pain.
