(100% is best)
The Pirelli Cinturato Cross is a tire designed for cyclocross use and available in both a Hard Terrain and Mixed Terrain (read our review) version. Both the Cinturato Cross Hard Terrain and Cross Mixed Terrain are only available in the cyclocross-specific 33-622 size. Pirelli also has gravel versions available which are very closely related to the Cross versions but seem to have a faster tread pattern with lower knobs and are available in bigger sizes in both the 584 and 622 wheel sizes.
The Cross Hard Terrain comes with a tubeless-ready reinforced 127 TPI casing with an extra layer of woven nylon that runs from bead to bead. The compound is Pirelli's SpeedGRIP compound that is formulated to provide a low rolling resistance, high tear resistance, and high wet grip.
As already mentioned, the Gravel versions of these tires come with a different tread pattern that should theoretically roll faster. We do not expect large differences between the Cross and Gravel versions in our tests as the construction and compound are the same.

| The CX/Gravel section is a multi tire size section, air pressures have been adjusted to the measured casing width. All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs. Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load. |

Conclusion
- Pirelli Cinturato Cross H 33
(100% is fastest - lightest - highest - strongest)
The Pirelli Cinturato Cross Hard Terrain is a reasonable fast cyclocross tire. Its main advantage is the greater knob height of both the center and edge knobs when compared to most other CX/Gravel bike tires. We're sure the Gravel version of this tire will be a bit faster (4-6% is our guess) at the expense of knob height.
The sidewalls aren't particularly puncture-resistant although the thickness of the sidewalls is better than most other tires in the same category. If these tires tick all your boxes then we're sure they will suit you well.
