Schwalbe Racing Ray TLE Addix SpeedGrip mountain bike tire on a rolling resistance test machine

The Schwalbe Racing Ray is optimized for front tire use and looks to be somewhat similar to the Schwalbe Rocket Ron that has been around for several years. Schwalbe suggests to pair the Racing Ray with the new from 2019 Racing Ralph (read review) that is optimized for use on the rear wheel. Using front/rear optimized tires seems to make sense for off-road riding as the loads applied to the front and rear tires differ greatly in most off-road use cases.

The Racing Ray is only available with the Addix SpeedGrip compound that rolls slightly slower than the Addix Speed compound but offers more grip in return. It's also only available with the stronger SnakeSkin/TLE casing. If you want more choices in compounds and casings, the Rocket Ron still seems to be the way to go as it's available in several LiteSkin/SnakeSkin casings and Speed/SpeedGrip compounds.

When we compare the Racing Ray to the Rocket Ron with the same casing and compound, both tires perform very close to each other in our tests. We do see a difference between high and low air pressures with the Rocket Ron being slightly faster at lower air pressures because of its more open tread pattern. At higher air pressures the Racing Ray is slightly faster because of the center blocks being closer together.

When we look at the suggested Racing Ralph/Racing Ray front/rear pairing, we see there aren't that big of differences between these tires. The Addix SpeedGrip compound on the Racing Ralph (read review) seems to be only slightly slower rolling. When rolling resistance between these tires is so close, we also have to wonder if the difference in grip can truly be noticed in real-life.

Feel free to leave a message about your experiences with the Addix Speed and SpeedGrip compounds as they have been around for almost 2 years now. We're very curious about real-life users that have used the older PaceStar and new Addix Speed and SpeedGrip compounds.
