Don’t skimp on the rubber.

One of the defining characteristics of Zipp wheels is their dimpled rims. Just like a golf ball, the dimples on a Zipp rim disrupt the air flowing over the rim surface in order to diminish the drag and make your wheels (and thereby YOU) faster for a given power output.

It stands to reason, that since all of Zipp's wheels got dimples, they looked for more places to utilize this proven technology. This is what inspired their Tangente dimpled tire. Dimples on a tire, are they serious? Absolutely yes. Few companies invest as much in wind tunnel time as Zipp, and it means they have the luxury to analyze every last little aerodynamic detail of a product. What they've learned in the tunnel is that tire design does indeed play a role in aerodynamics. It goes beyond the obvious value of tire width, with tread texture and the transition style of rubber-to-casing also playing a role in aerodynamics. They determined that (not unlike dimpled rims vs. smooth ones), moderate tread provides superior aerodynamics to slick tread or really rough tread. So they began testing dimpled tires and the result is the Tangente -- the only tire whose aerodynamics complement the aerodynamics of your wheelset.

Just because the Tangente Clincher Tire is aero, you don't sacrifice the all-important ride quality you can expect from a high end tire. In fact, Zipp worked side-by-side with Vittoria for 14 months to refine the tread models, the rubber compound, and the tooling to find the perfect balance of low rolling resistance, durability, suppleness, grip, and -- of course -- aerodynamics. And best of all, Zipp's dimpled design significantly reduces the stress within the tread, in comparison to other tires, which reduces the stress cracking of the tires through age and use.

According to Zipp's tests, the Tangente Clincher Tires will save you 1-3W of energy in comparison to other high end tires. They're handmade from the finest 290 TPI corespun casing and silica tread compounds available -- in essence combining the highlights of the Vittoria Corsa CX (its supple casing) with the best of the Continental GP4000 (its cornering characteristics and road feel). The Zipp Tangente is available in 700x21mm and 700x23mm.

The old-model Zipp clincher tire

  • Familiarity:I've put it through the wringer

Zipp's updated its Tangente line so this one's going out of production. But for $40 it's an unbelievable value. Buy them.

Whether these tires are much more aero than the competition I cannot say--the dimples purportedly save one watt. That won't win you any races, but every watt helps I guess. The 290 tpi brings the tire fairly close to the best racing tires in terms of suppleness. What little information I could find reported that the rolling resistance of the Tangentes was pretty low. So these aren't in the same class as the, say, Vittoria Open Corsa Evo tires; however I have no complaints especially when these are paired with latex tubes. Comfy and fast. The rear tire will probably wear out somewhat faster than a Conti GP4000s will, but I like these better for racing. The front tire seems to show barely any wear after some thousand or so miles.

I have to confess that I'm going to miss these tires. My rims are fairly narrow and this iteration of the Tangente offered a 21mm width that worked perfectly with my Zipp 60s and Boyd Rouleur wheels. The newer Zipp tires are too wide for what I need and would disrupt the airflow of the wheel. Wider may be better, but if aero advantage is what you're seeking then you need to consider the wheel and get a tire that won't mushroom out.

Is this a tubeless clincher tire?

Is this a tubeless clincher tire?

No, this is not "tubeless".

There is currently one tire – the Hutchinson Fusion 2 Tubeless – that offers the unique carbon/rubber tire bead matrix that can seal with a rim adequately to hold air.
