Monster, Monsteur, Monstour , 26/29+ and Expedition and Adventure bikes

Oh, it's terrific setup on the Kona. I was referring to one time where I put an 80mm and mary's on a road bike. That was awful, or at least about 10 times twitchier than I like.
Honestly, I think you'd have to wider than the Mary's to get to full benefit.
Something like 680-730mm wide, as I recall the Mary's are 640mm
