CX bike morphing into Gravel bike...

[phutterman]

I use those Xplor MSO tires on my CX bike most of the year for general dirt/mixed terrain use, and then throw narrower tires on it for cross season (knobbier if it's muddy, which it never is, and a file tread in back most of the time otherwise). Knobby enough for the dry dirt around here, and great float and volume.

Only time I really regretted it was on a ride (the so-called Tainthammer, a central CA 'gravel' thing) that turned out a lot muddier than I'd expected and where I'd have been much better off with like 32 or 35 slicks.
