Now that I have your attention;
I put a set of 700x38 Vittoria Randonneur Hyper on my Mostorcross bike. These tires are light, smooth, fast and supple.
I rode 42 miles of mostly crushed limestone plus a mix of chip-seal, pot-holed asphalt and broken concrete,
It was bliss. Like floating on a cloud while keeping a solid road-bike pace. These tires will cover any firm and dry surface without slowing. Who needs a emaciated tire that can't keep going when the real adventure begins.
I'll ride a fatty any-day.
