Part of this push comes from the addition of more demanding cross country courses and a push for more utility and adaptive design.Knob wear is consistent with the mileage I put on the Barzo’s, and knob integrity is still intact.
The 4C process is said to offer versatility to the tire, by allowing for separate base and surface compounds, in both the center and side areas of the tread.
I weigh 220lbs and believe these tires would make those who are lighter on wider rims very happy and quick. In both cases the rear tire tended to break loose early, meaning you had to plan ahead during rapid speed scrubs, and really focus on keeping evenly-weighted body position during tough uphill grunts. He has been involved in nearly every aspect of the cycling industry: from turning wrenches, store design, clothing production and bike park creation.
Vittoria’s Barzo ticked all the right boxes for me; Multi-conditional extended wear and race ready. Next purchase will be Mota up front and move the Morsa to the rear. Only in super dry, sandy conditions is where I noticed a hiccup in traction.Often, we’re always compromising with our gear to suit our riding style, whether it be for: weight > durability, speed < grip, or what have you. Sumner has also done extensive gear testing and is the author of the cycling guide book "75 Classic Rides: Colorado." While the tread puncture resistance is very high, sidewall puncture resistance is very low with a score of only 4 points.When calculating the Puncture Factor score, we also take the tire thickness into consideration because thickness also provides puncture resistance.
Keep reading to find out how it performed.This Vittoria Mezcal has a low profile, densely spaced knob configuration with a defined center ridge tread for low rolling resistance.Where Mtbr didn’t love this tire was under hard straight-line braking and while trying to power up steep, loose terrain. I recently purchased a Morsa(also a fast tire)to run up front which brakes more predictably but is not as predictable in the corners. Vittoria’s Barzo tread is sharp, designed for wet conditions and technical cross country racing. The sidewalls are much thinner with a measured maximum width of 0.9. LOVE LOVE LOVE these tires…Did you try a Dynaplug or Innovations Bacon Strip? Vittoria Mazza Tire Details • 4C Graphene rubber compund • Tubeless ready • Sidewall protection • Trail and Enduro casing options • Sizes: 29 x 2.4" or 2.6", 27.5 x 2.4" or 2.6" For most of my rides I run the Barzo at 22-24 PSI and found that gives the most traction and cushioning, but I have ventured into the 17-19 PSI area and suffered zero burps and minimal sidewall folding.Cross country tires miss a large segment of the trail riding community, often seen as narrow, not grippy, paper-thin, race-only rubber.
The fact that both tires failed along the center tread on the same trail section likely means it was a particularly sharp rock (and/or some particularly poor bike piloting). Indeed, like all the tires in this class, a certain amount of line choice precision is required. The straight line braking is squirmy to the point I second guess the corner speed even though the grip is there. The net effect is a tire that’s comfortable and predictable at aggressive lean angles, but not at the expense of its ultimate goal — crossing the finish line first. The sidewalls, on the other hand, are much more flexible. The measurement that should be looked at is the ETRTO which is 55×622. And in nearly every condition I threw at it, the tire performed solid.
