Specialized renewed their mountain bike tires in 2021 and introduced the T5, T7, and T9, versions where the T(number) stands for the hardness of the compound. The S-Works Fast Trak 2 Bliss Ready T5/T7 comes with a dual compound with the T5 compound (faster) in the center and the T7 compound (grippier) along the edge of the tire.


The S-Works version of the new Fast Trak is the only version with a dual compound. Also available are CONTROL (more protection) versions that come with a single compound and are available in either the T5 compound for more speed or the T7 compound for more grip. An even more protected GRID version is also available, but that one is only available with the T7 compound.


The new "T versions" of the Fast Trak also come with a redesigned "Block-In-Block" tread pattern that, according to Specialized, is an overall improvement over the older tread pattern that we've known for quite some time. We're not sure if the casing has changed, but it's still specified as 120 TPI for the S-Works version and 60 TPI for the CONTROL and GRID versions.


The S-Works version that we've tested is the lightest version of the Fast Trak, but we're not sure if it's also the fastest considering it comes with the slower T7 compound along the edge of the tire. Let's just dive into the test results and see if we can spot some surprises.

The Specialized Fast Trak S-Works 2Bliss Ready T5/T7 isn't the fast XC tire we hoped it would be. At the lowest air pressure of 25 psi / 1.7 bars, rolling resistance comes in at 30.5 watts (single tire) which is more than 10 watts higher than the Continental Race King Protection that offers a similar knob height. We're also not impressed by the performance in the puncture tests, with a low score in the tread puncture test and a very low score in the sidewall test.


When we compare the new S-Works Fast Trak T5/T7 to the older pre-Gripton compound version we tested back in 2016 (read our review), we see the older version outperforming the newer version in all our tests. We're also surprised this new version of the Fast Trak comes from a different factory, but we're not sure how much the factory change has to do with the lower-than-expected performance.
