Apologies, my title should say gravel riding.
I am on a BMC Roadmachine 01 Three with Roval C38 Wheels (tubed) w/ Conti GP5000 28mm tires now.
I can go up to 33mm wide with my frame.
Leisurely solo rides. Not hunting KOMs or racing.
Gravel could mean rail trails (tightly packed pea sized rocks). The bike is too compliant for anything more aggressive than that and would rattle my brain
I am not riding in the mud.
