No holds Barzed.

The Vittoria Barzo TNT Tires are just what the wagon-wheel set ordered. They're fast and smooth, but tight and grippy on hard, dry surfaces. Lean-dependent sipe angles mean the hard cornering grip doesn’t kick in until the tire is leaned over, which keeps rolling resistance to a minimum. Counter V-formation channels ease the self-cleaning of mud, dirt, and debris, so the tire sheds quickly if you find yourself in the sticky stuff.

Tread isn't the end-all be-all, though. Almost as important is the casing underneath. Vittoria TNT casing is made from 120 TPI cloth, which is quite supple by mountain bike standards, so you'll have better grip and less rolling resistance. The sidewalls are also reinforced with nylon in order to minimize cuts and folding when riding at low pressure. The Barzo tires come in both 2.1-inch and 2.25-inch widths, so you can go burlier or slimmer as you see fit. Holding the tires onto the rim is a TNT Talon tubeless-compatible bead that also lets you run tubeless if you prefer.

Eats Loam. Enables Shred.

  • Familiarity: I've put it through the wringer

Currently I'm living in dry dusty conditions in Durango, CO, but when I lived in New Hampshire the barzo was my favorite tire. The rounder tread profile allows lots of knobs to grip the loose spongey dirt well. Also it sheds mud well because the knobs are decently spread out.

My New Go To

  • Familiarity: I've used it several times

Unlike Rob below, I'm actually running this as my rear tire. I have a Saguaro up front. I'm on a carbon hardtail, with Reynolds Carbon Black Label wheels. This tire was very easy to bead and setup tubeless. Truth be told, my floor pump broke and I actually beaded this tubeless with a hand pump! It was a cinch. This tire rolls very fast and grips well. I'm about 100 miles in and have had zero issues with pressure, punctures, or grip. Vittoria knocked it out of the park with this guy.

Great front tire for loose over hard

  • Familiarity: I've used it several times

I've been riding the Vittoria Barzo TNT tire on the front of my Santa Cruz Tallboy LTc for the last couple weeks and am quite impressed by it's traction on loose-over-hard conditions (much of what we find in the rockies). The 2.25 has pretty good volume for it's size, and I haven't been left wanting for a wider option as of yet.
