The Schwalbe Racing Ralph Super Race with Addix Speed compound now is the fastest version of the Racing Ralph you can buy. Schwalbe introduced their "Super" casings back in 2020 with a big marketing campaign they called "The Decade of Super". As they're talking about a decade, we're going to assume this will bring some stability to their lineup for the next 10 years. Hopefully, this gives us the ability to catch up and test some of these tires before they get replaced by the next version.

Schwalbe's lightest casing now is the "Super Race" casing which is a 3 layer 67 TPI casing that's still much stronger than the 2 layer 127 TPI LiteSkin/TL-Ready casing that Schwalbe offered in the past 10+ years. According to Schwalbe, they went with a triple layer 67 TPI casing as it offers better stability and sealing when used in a tubeless set up which is now much more common than it was just 5-10 years ago.


Although the Super Race casings are relatively easy to set up tubeless, and they hold air well, it's still recommended to regularly check your tire pressures. If you want trouble-free tubeless operation, it's recommended to step up to the Super Ground casing that features an extra layer of cut-resistant material that also helps to keep the air in.


The Super Race casing is only available with brown/transparent sidewalls (for now at least) which probably isn't the right look for everyone. The available sizes are also quite limited as they only carry these in the 29x2.25 and 29x2.35 sizes (read more about the size in the conclusion).

The Schwalbe Racing Ralph Super Race is a solid performer in our tests and it's quite clear the latest edition of the Racing Ralph has been beefed up at the expense of increased weight and rolling resistance. We do think the Super Race casing is a bit of a missed opportunity as there is only a very small difference between the Super Race and Super Ground casings. We would have gone with a triple layer 127 TPI casing instead of the 67 TPI casing.


We now have the same situation with the Schwalbe casings that also exists with their Addix "Speed" and "SpeedGrip" compounds: the differences are hard to find. In our opinion, the Super Race casing combined with the Addix Speed compound should have been one of the fastest tires out there, just like the 2014/2015 Racing Ralphs with the old PaceStar compound were.


The weight of the Racing Ralph also keeps on increasing with every new version they release. The Super Race 29x2.25 version now has a specified weight of 640 grams, while back in 2014/2015, the TL-Ready version had a specified weight of 535 grams, and the TLE version was 605 grams. On top of that, they downsized the casings and the 2.25 version is now close to the size of the older 2.10 version.
