In our package of Specialized tires we found these versions of the Fast Trak. A “2Bliss” S-Works version no less.
These are similar to the non-S-Works “LK” version, which we also will be testing, however, these have a lighter, slightly narrower casing with a dual compound tread. The compound is noticeably different in the middle, being much harder than the edges.
As you can see from the images above, these are narrow tires for “go fast” riding. The weight is also in the “go fast” territory at 520 grams each. We will be testing these tires on the wheels pictured, (Easton XC-1 SS wheels, also on test) and we should have a First Impressions post up with a race report from the 12hrs of Temecula soon.
Stay Tuned!











Nice – I’ve been running a Python tubeless on the back of my Sultan for the past 3 months, including the past few races down here in Miami – and have been pretty pleased with it. The dimensions are about the same – but I would give the nod to this one based on weight. Interested to see the durability factor – how well the sidewalls will hold up to upper-20 to low-30 psi range while tubeless.
Ran a Fast Trak on the rear on a 26 and was impressed with it. It hooked up pretty well for a fast roller. Should make for a good race tire in the right conditions.
520 g is the Specialized weight or the really weight by you ?
This tire seems to be very interesting for my ride. I hope that your last conclusions will be good.
Tbow: 520 grams is the weight on my digital scale.
I just got 6 of these tires in and weighed all of them. They ranged from 521 to 560 grams. Only one was the 521 and another 534, and the rest were 550 to grams respectively. Bring a scale if you want the lightest ones.
