Ardent 2.4 front, it’s massive and helps with comfort on the front and is a great tyre, rolls well, grips well in most conditions. May put the 2.4 ralph on the front if it gets really dry in summer but not good in the slop…
Ardent good on the rear too, 2.4 if single speed or smaller if using gears as the 2.4 interferes with the front mech.
Crossmark good on the back too especially when a bit dryer.
Mud-x or beaver in the nasty mud.
Thats what I use on my rigid swift anyway…
