Specialized S-Works Turbo Tires

Specialized S-Works Turbo Tires

The first time a tire ever impressed me, it was a 28mm-wide Specialized Turbo. Reagan was in office. It was my first folding clincher and its improvement on my bike’s handling and rolling was enough that I vowed to buy a set of tubular race wheels. Basically, I decided that if a Mustang was that much better than my Corolla, I needed a Lamborghini.

Since then, everyone has upped their tire game to the point that I haven’t ridden a 23mm tire I disliked enough to comment on in more than five years. It’s also fair to observe that while Specialized helped lead a revolution in clinchers, they’ve made some tires that were frozen-pizza awful.

They also spent some serious money on rolling resistance research and when they got what can only be described as bad news, rather than doubling down on marketing double-speak, they overhauled their entire tire program. I like to point to moments like this when people want to accuse Specialized of building their entire company on exhaust and reflective devices.


We’re a a couple of years into that overhaul now and for the last two months I’ve been riding the new S-Works Turbo. I’m running it on Zipp 303s in a steel frame. This generation of the S-Works Turbo is 220 tpi and supple as a dress shirt. It comes in three widths: 22, 24 and 26mm. I wish they offered 28s and 30s, too. I’m riding the 26s and on the awful roads in Sonoma County, they are the difference between shoulder pain and fun. On the label they suggest a pressure range of 110 to 125 psi, but I disregarded that the way I disregarded the inscription that says “for racing only.” Without bothering to smirk, I’ve been pumping them up to between 85 and 90 psi in the front and 90 to 95 psi in the rear. Were the roads here better, I might run a bit more pressure, but I paid a lot for my dental work. The only flat I’ve gotten has been from a thorn I found while picking blackberries at the side of the road. Given the quality of the blackberries, it was totally worth it.

That this tire only goes for $55 is a selling point in itself. That’s cheap enough among high-performance clinchers that it’s not unreasonable to run them in all but rainy conditions, when water will cause any tire to flat more readily.

Specialized refers to the rubber compound as Gripton, which is cute enough, but objectively all we know is that it’s a proprietary blend that is high on grip and low on rolling resistance. Anyone who has read a bit about rubber knows that those two qualities are inherently at odds. I’d love to know what the durometer of the rubber is so that I can better compare it to competitors, just for my own edification.

As a reviewer, every now and then you try something that causes you not to move on to the next sample. This is one of those occasions.

    Try a pair of Compass Bicycles’ Chinook or Cayuse Pass tires. Or if they fit on one of your bikes, a larger set. You’ll regret depending on handouts from Specialized …

    Well, Padraig, you will no doubt be pleased to hear of the arrival of a 700×28 SWorks Turbo. Due shortly.incidentily, a 22 is in the works ad well.

    Curious to hear how many miles you have on the S-Works Turbos. What’s the wear like – predictable, alarming or surprisingly long-lasting?

      I’ve got about 800 miles on mine and they’re still going strong. And I’ve ridden them on some pretty crappy roads and through some crazy construction zones.

    All: thanks for your comments. Keep ’em coming.

    Cash: No, I never really wrote a review of the bike. I’ve written a lot about it but never did an actual review. Seemed sort of pointless; I mean, who was going to be surprised that I love the bike. That said, if a few folks express interest in this space to see that piece, I could be persuaded. It would be fun to write, so there’s that.

    Paul: I hadn’t gotten a press release about the new sizes. The 22 seems pointless, but the 28 makes me drool.

    Mark: I’m north of 600 miles on them and they are going strong. Barring a big cut, I’ll get more than 1000 miles out of them.

    Dave: Well, yes and no. I like that there is one, but I haven’t tried it. Might have to talk to them about it, though.

    Just got 1600 miles out of a set of 24’s. Switched to 26’s this week. Got 100 miles on them they handle as well or better than the 24’s and a bit more cushy on rough roads. I like them.

    How easy were they to fit to the rims? I have a set of Enve 2.2 SES tubeless wheels and have been using Vittoria tyres but they are a nightmare to get on the rim before seating them. I’m looking to change and the choice is the S Works 26 or the Hutchinson Sector.
    Any thoughts appreciated.
