- Schwalbe Pro One Aero TLE (Rear) 28
(100% is best)
The Schwalbe Pro One Aero is a new tire designed for optimal aerodynamics. Unlike many other tires, the Pro One Aero is available in both a Front and a Rear version, allowing for specific optimization of each tire's unique properties. The Front version boasts an even more aerodynamic profile, while the Rear version prioritizes low rolling resistance and better puncture resistance.
The weight is also clearly different: the specified weight of the Front version is 235 grams, while the Rear version is 270 grams. This difference is due to the puncture resistance and thickness of the tread. The idea here is that the front tire does not need to be as puncture-resistant and wear-resistant because the load is lower than the rear wheel. In practice, we also see that rear tires wear out faster; with a Pro One Aero set, the front and rear tires should be worn out roughly simultaneously.
We've known the Pro One series from Schwalbe for a while now, and the regular Pro One TLE (read our review) is probably the most well-known in this series. The regular Pro One TLE is a classic all-round tire suitable for all conditions throughout the year. Schwalbe also has the Pro One TT (read our review), which is for time trials and we found it to be very thin and fragile. We wonder where the Pro One Aero fits into this series, and our tests will provide a very clear answer.
The Pro One Aero is built with the well-known Schwalbe Pro One recipe: a 127 TPI Super Race casing and Addix Race compound. We do see a notable difference in the anti-puncture layer, which is the "RaceGuard" material on the Pro One Aero but "V-Guard" on the regular Pro One TLE. As far as we know, the V-Guard material was Schwalbe's best choice, and we mainly saw the RaceGuard material on Schwalbe's mid-range tires.
While the regular Pro One TLE is available in many sizes, the Pro One Aero is only available in the 28-622 size for both the front and rear versions. Schwalbe also states that modern rims with a larger width (20-25 mm) should be used for the best aerodynamics.
Let's review our tests and see where to place the Pro One Aero in the Pro One lineup.

| The Road Bike 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
- Schwalbe Pro One Aero TLE (Rear) 28
(100% is best)
In most of our tests, the Pro One Aero Rear performs in line with the regular Pro One TLE (read our review), but the compound on the new Pro One Aero is clearly a different mix. We see this in both the rolling resistance test and the wet grip test, where a different trade-off has been made: rolling resistance is slightly higher, but the wet grip, where the regular Pro One TLE fell short, is much better on the Pro One Aero.
Furthermore, we see that puncture resistance is virtually the same for both the tread and sidewalls, and we cannot find the difference between Schwalbe's RaceGuard and V-Guard. The tire thickness is also the same, and when we compensate for the different sizes we have tested of the Pro One TLE and Pro One Aero Rear, the weight also seems to be roughly the same.
Unfortunately, we cannot test aerodynamics, but the Pro One Aero Rear comes very close to the regular Pro One TLE in many of our tests. We expect the Front-specific version to show a more significant deviation since it is thinner and lighter. Just a little more patience, but we hope to test the Pro One Aero Front very soon as well.
