Schwalbe Racing Ralph 2019 TLE Addix Speed road bike tire on a rolling resistance test machine

The Schwalbe Racing Ralph has been around for as long as I can remember. Starting with the 2019 model, the tread pattern has been redesigned. The 2019+ model now has a completely new tread pattern that is more optimized for use on the rear wheel. The updated tread pattern makes it a completely new tire of which only the name is the same. The rear wheel optimized tread pattern makes sense as many people were already using the previous model Racing Ralph on the rear with a grippier tire like the Nobby Nic or Rocket Ron on the front.

Schwalbe launched the new Racing Ralph as a pairing with the Racing Ray that is optimized for front wheel use. The new Racing Ralph/Racing Ray combination seems a good replacement for the classic Racing Ralph/Rocket Ron pairing. To further indicate the intended front/rear use of the new Racing Ralph and Racing Ray, the Racing Ralph is only available with the faster Addix Speed compound and the Racing Ray only with the grippier Addix SpeedGrip compound.


From a technical standpoint, it's interesting to see Schwalbe only offers the new Racing Ralph with the Addix Speed compound instead of both the Speed and SpeedGrip compounds that they did with the previous generation. Furthermore, they also dropped the LiteSkin versions and now only offer SnakeSkin/TLE versions in just 4 sizes. We're not sure if other versions will be released in the future or if this is the new direction Schwalbe is going for the future.

Conclusion

Schwalbe Racing Ralph 2019 TLE Addix Speed  mountain bike tire on a rolling resistance test machine

In 2019, we're still not convinced by the Addix Speed compound as it is not as fast as the older PaceStar compound that Schwalbe used up to 2017. Schwalbe made big claims about the Addix Speed compound being faster than the PaceStar compound but our tests once again indicate that's not true. To see this for yourself, you can now compare 3 generations of Schwalbe Racing Ralph TLE side by side on our website here: Racing Ralph TLE 2015 vs Racing Ralph TLE 2017 vs Racing Ralph TLE 2019


When we compare the new 2019 Racing Ralph to the 2017 Racing Ralph (read review) that uses the same compound, we see performance on our tests is very close. One positive thing is we now at least got a tire that weighed less than the specified weight. With such small differences, it's going to be up to your individual use case whether the new Racing Ralph is going to be an improvement or not.
