The Vittoria Corsa Speed TLR (read review) has been the fastest tire on our site since the beginning of 2016. With the release of the new Graphene 2.0 compounds, Vittoria also updated the Corsa Speed TLR with the new version of this compound. Vittoria claims they once again improved rolling resistance, but they also claim the Graphene 2.0 compound increases wear-life and grip on the sides.

Back in 2016, Vittoria started with just a 23-622 version of the Corsa Speed TLR while the 25-622 version was made available later in 2017. With the 2.0 version of this tire, Vittoria released both a 23-622 and 25-622 version right from the start. Vittoria also dropped the grey colored sidewalls and have gone for black sidewalls this time around.

Because our preferred size is 25-622, we've opted to test the 25-622 version of the Corsa Speed 2.0. When comparing the 1.0 and 2.0 of the Corsa Speed G+ TLR on our site, keep in mind that bigger tires usually have a slightly lower rolling resistance at the same air pressure.

Weight. The specified weight of the 25-622 version of the Corsa Speed G+ 2.0 is 240 grams. Our sample is quite a bit lighter at 227 grams which is something we always like to see when buying tires.

Size. On our 17 mm inner width rim, at an air pressure of 100 psi / 6.9 bars, the 25-622 Corsa Speed G+ 2.0 measures 27 mm wide and has a height of 24 mm. Compared to the 23-622 Corsa Speed G+ 1.0, the new 25-622 version has grown exactly 2 mm in both width and height.

Tire Thickness. Total tire thickness at the center of the tread comes in at 1.8 mm compared to the 1.7 mm thickness of the previous version. With such a small difference we can assume no change has been made to the tread thickness. 1.8 mm is quite thin when compared to all-round tires that often come in at 2.5-3.0 mm. The thin tread indicates this tire is really optimized to provide the lowest possible rolling resistance.

The sidewalls have a thickness of 0.85 mm which is the same as the previous version and in line with most other tires with cotton casings.

In the rolling resistance tests, the Vittoria Corsa Speed G+ 2.0 proves it's the fastest tire in the world with a rolling resistance of just 7.0 watts at an air pressure of 120 psi / 8.3 bars. The previous version of the Corsa Speed already was the fastest tire on our site with a rolling resistance of 7.7 watts at 120 psi / 8.3 bars.

When we look at lower air pressures, we see the new version of the Corsa Speed really stretches its legs with a rolling resistance of just 9.3 watts at the lowest tested air pressure of 60 psi / 4.1 bars. The previous version came in at 10.9 watts here so that's a huge improvement.

The Corsa Speed isn't made to provide a high puncture resistance and it shows in our puncture tests. In the tread puncture test it scores just 8 points which is the same as the previous version, but a lot lower than the 10-12 points most all-round tires with puncture strips under the tread achieve in this test. When using this tire set up tubeless, it should provide decent puncture resistance as the sealant should seal most small punctures.

In the sidewall puncture test, the Corsa Speed G+ 2.0 scores 4 points which is 1 point less than the previous version. A difference of just 1 point is not enough to draw any conclusions as it can also be attributed to the margin of error of this test.

Conclusion

Vittoria Corsa Speed G+ 2.0 (TLR)

(100% is fastest - lightest - thickest - strongest) Performance compared to all other road bike tires (100% is fastest - lightest - thickest - strongest)

Unlike the regular Corsa G+ 2.0 that actually had a higher rolling resistance than the original G+ 1.0 version, The Corsa Speed TLR G+ 2.0 does have a ~10% lower rolling resistance than the previous version. With a rolling resistance of 7.0 watts at 120 psi / 8.3 bars, Vittoria has cemented their number 1 position on our site and we have to wonder how much lower rolling resistance of road bike tires can go.

Rated 5 out of 5 as that's the only possible rating when you strengthen your number 1 rating on Bicycle Rolling Resistance. We're really curious about real-life experiences with these tires as well, feel free to leave a comment and let us know about durability, grip, and puncture resistance.
