I've never seen a gravel bike up close but I know quite a few guys who are thinking about them for "training" purposes. Back in my day we slapped on a set of 1.85 Panaracer Fire XC on a hardtail or burley Continentals on a touring bike.Glad you missed the fence posts... that would have been bad.
Gravel biking FTMFL
As @rockofullr Said, E.13 coil post... completely serviceable at home with standard tools. No bleed required.
XC is still in there too. I did see some people use gravel bikes for parts of the AZT...![]()
