According to Schwalbe, their new One series of road bike tires are the fastest rolling tires they've ever manufactured, they even built a brand new factory to manufacture these tires. On test today, is the Schwalbe One V-Guard 700 x 25C which is the clincher version of the One. It's also available as a tubular or tubeless road bike tire. It seems like Schwalbe removed the Ultremo series from the 2015 model line-up, at least they don't show up on the official Schwalbe website anymore. So everybody that loved the Ultremo has to move up to the Schwalbe One.

The biggest improvement over the Ultremo is a new compound: OneStar. This compound was developed specifically for low rolling resistance. It's a triple compound which is based on special polymers that have only recently become available. Schwalbe says this results in a great improvement in the trade-off between durability, wet adhesion and rolling resistance. However, it does is 10 grams heavier than the Ultremo of the same size, this is attributed to the amount of material used.

Size and Weight Measurements


Size and Weight Measurements (Bike Wheel: 622x17C, Pressure: 100 psi / 6.9 bar)
Specified Weight 225 grams
Measured Weight 243 grams
Measured Width 27 mm
Measured Height 24 mm
Total Tire Thickness Center 2.9 mm
Total Tire Thickness Sidewall 0.5 mm

Unfortunately, this particular Schwalbe One is overweight by quite a bit: 243 grams versus a claimed weight of 225 grams. This means there is more material and rolling resistance will be higher as a result. The measured width is 27 mm. Height is 24 mm.


Rolling Resistance Test Results


Rolling Resistance Test Results (Speed: 29 kmh / 18 mph, Load: 42.5 kg)
Inner Tube Conti Race28 (100gr butyl)
Rolling Resistance 120 psi / 8.3 Bar 12.3 Watts
Rolling Resistance 100 PSI / 6.9 Bar 12.8 Watts
Rolling Resistance 80 PSI / 5.5 Bar 14.0 Watts
Rolling Resistance 60 PSI / 4.1 Bar 16.6 Watts
Rolling Resistance Coefficient (Crr) 120 psi / 8.3 Bar 0.00369
Rolling Resistance Coefficient (Crr) 100 psi / 6.9 Bar 0.00384
Rolling Resistance Coefficient (Crr) 80 psi / 5.5 Bar 0.00420
Rolling Resistance Coefficient (Crr) 60 psi / 4.1 Bar 0.00498

At an air pressure of 120 psi, rolling resistance is 12.3 Watts. At 100 psi, it sets a new record in the rolling resistance test, beating the Continental Grand Prix 4000S II by 0.1 Watts. Unfortunately, it can't keep up this strong performance. At air pressures of 80 and 60 psi, rolling resistance is 14.0 Watts and 16.6 Watts respectively. This is 0.3 and 1.1 Watts higher when compared to the GP4000S.



Puncture Resistance Test Results


Puncture Resistance Test Results (higher is better)
Puncture Resistance Tread 12
Puncture Resistance Sidewall 4

Performance in the puncture resistance test is average for an all-round summer tire. With a puncture resistance score of 12, it beats the GP4000S II by 1 point. If we take the low rolling resistance into consideration as well, a score of 12 is very good. It looks like Schwalbe really hit the sweet spot with the One.




Conclusion

It really is a shame this Schwalbe One has so much overweight, I'm pretty sure if it came in at the claimed weight of 225 grams, it would have beaten the Grand Prix 4000S II at 120 100 and 80 psi, I'm not sure about 60 psi. A score of 12 in the puncture resistance test is also very good for such a fast road bike tire. It's clear that the Schwalbe One is a very big improvement over the Ultremo. I don't think anyone is going to miss that tire when you can get the new Schwalbe One.


I'm glad Schwalbe wasn't lying when they said this is the fastest road bike tire they have ever made. If you're looking for a fast road bike tire and can get hold of a sub 225 grams Schwalbe One V-Guard, definitely get it!
