24.7 W · rank 11 of 20 comparable XC tires
8 W behind the best value in the same test series. Fewer watts is better – every watt saved stays in the drivetrain.

Width, casing, compound and pressure – every value on this page follows your pick.
Width, casing and compound decide how a tire really rides. We only show what was actually measured – and label estimates honestly.
Reference: recommended pressure 24 psi (1.65 bar) – an assumption, not a test pressure.
More pressure: less rolling resistance, less grip, less comfort. Tougher casing: more protection, more weight. Softer compound: more grip, more rolling resistance.
Modelled values are assumptions based on the stated measurement points – not a lab test.
Editorial assessment on a 1–10 scale. Grip index: 6.9
These grades describe the tire model, not one specific width or compound – no reliable per-version grades exist.

67 points · rank 10 of 20 comparable XC tires
5 points behind the best value in the same test series. More points means more compound grip on smooth surfaces.
Weaker in comparison
747 g · rank 15 of 20 comparable XC tires
155 g behind the best value in the same test series. Fewer grams is better, but usually costs casing stability.

Bicycle Rolling Resistance
November 2025In Bicycle Rolling Resistance's lab test, the Barzo XC Race measures 24.7 watts of rolling resistance, 34 points for puncture protection and 67 points for wet grip. Overall score 4.0 out of 5 ("Recommended") as an all-rounder without specific demands.

November 2020BikeRadar tests the Barzo TNT as an aggressive XC tire with good support and grip in most conditions. It works best up front paired with a faster-rolling rear tire; on very dry trails it is almost overkill.
To the sourceMTB-News.de
September 2018The Vittoria Barzo was tested alongside the Mota in trail and enduro use. As the lighter, faster-rolling of the two tires, it suits XC and marathon-oriented riders particularly well. Grip remains convincing on dry terrain.
To the sourcePinkbike
June 2015Pinkbike positions the Barzo for technical XC terrain rather than as a pure lightweight race tire. The continuous center ridge keeps rolling speed up despite the open tread, and the sturdy TNT casing mounts tubeless without fuss.
