Road Bike Tire Test: Schwalbe Pro One TT TLE Addix

The Pro One TT TLE with Addix Race Single compound is the fastest option within the new Pro One lineup from Schwalbe. Together with the TT version, Schwalbe also released a regular TLE (read review) version and a tube-type (read review) version for cyclists that still prefer to use inner tubes. The Pro One TT TLE is made for time-trials, triathlon, or other competitions where you need every last bit of speed.

Compared to the regular Pro One TLE that is more of an all-round training/racing tire, the TT comes with a much thinner tread and no anti-puncture strip under the tread. Schwalbe also went from the Addix Race Multi compound to the Addix Race Single compound. This tire uses a single compound because only the compound that gives the lowest rolling resistance is used. Vittoria does the same thing with their Corsa Speed (read review) tires which are currently the fastest tires out there (road bike overview).

Although the Pro One TT TLE looks like a cotton casing tire, it uses the same 2x127 TPI casing as the other Pro One's. The sidewalls have simply been painted/coated in a yellowish shade to give it that classic/cotton look. I haven't found any info on whether a black version will be made available as well.

The Schwalbe Pro One TT TLE is one hell of a fast tire! It does come in slightly behind the Vittoria Corsa Speed G+ 2.0 TLR (read review) that currently is the fastest tire on our site.

When looking at the other results from our tests, we see tread thickness is even less than the Corsa Speed and the tread is also easier to penetrate. Weight is nearly the same for both tires. The only positives over the Corsa Speed are slightly stronger sidewalls and a wider tread.

We had a hard time deciding between a 4, or a 5 out of 5 rating because the Pro One TT is this fast. When looking objectively at both the Pro One TT and Corsa Speed, we feel the Corsa Speed is just a tad better when you simply need the fastest tires. We also know puncture resistance of the Corsa Speed is already borderline and going even lower may just be a bridge too far.
