The Paul brakes are great, although no better than well set-up BB7s.
I just swapped out an old pair of the same Gravelkings that I had on various bikes across a 4 year period. I think I had maybe 1 puncture per year on them. I'm always surprised to hear that people have problems with flats.
It's incredibly satisfying to have a bike that's so, functional.
Just swapped a few bits for a ride in Epping tomorrow vs earlier this month touring through France.
