Just come back from 22 miles first ride on a Chronicle. It’s on the front of my Diamond Jones with truss fork. I’m running 45mm Dually rims front and rear. I was running a 2.4 Chunky Monkey, front and rear.
It comes up 75mm wide on the Dually at 20psi.
Rides much better than the CM, loads more grip, was running about 20psi which is not ideal but I have a quite a few road sections in-between so didn’t want to keep dropping pressure then re-inflating. Even with the high pressure loads more grip in all kinds of trail conditions mud, water, rock, wet grass and hard pack.
It is absolutely massive on the bike, couldn’t see me changing from 29+ for any reason now. Eats the trail up.
