Tangente Clincher Dimpled Tires

Every last detail engineered for speed

• 14 months of aerodynamic development…the first windtunnel designed tire
• 1-3 watt power savings
• 21mm width is the optimal blend of aerodynamics, rolling resistance and durability
• Supple 290 tpi casing
• Corner-hugging silica rubber compound
• Puncture resistant construction

• Includes tire pressure chart to optimize rolling resistance by rider weight and front/rear use

The unrelenting speed enthusiast understands the details. 
Zipp knows the tire is the leading and trailing edge of your wheel’s airfoil and affects aerodynamic performance by up to 30%. And you want that speed all for yourself.  Conventional wisdom says a time trial tire should be a smooth as possible to keep the air flowing over the wheel. But the reality is, smooth or not, the inherently “un aero” round cross section of the tire, (remember, the perfect shape on a leading edge is elliptical, not round) punches the air away from the rim with all the finesse of a flying brick. The only solution? Create an aerodynamic boundary layer over the tire to trip air into flowing like it’s on an airfoil. In short, dimples.

 

14 month’s worth dimple plotting, modeling and calculating, plus 2 trips to the wind tunnel to create a dimple pattern with exactly the right surface roughness for boundary-layer formation. Over a year’s worth of hard labor to save you 1-3 precious watts on race day.

Where the rubber meets the road
While the Tangente is the most aerodynamic tire in the world (and the only one developed in the wind tunnel) it’s not just a delicate, special-mission TT tire. It’s got the guts of a hardened road warrior thanks to our partnership with Vittoria. Their expertise helped us optimize the handling, responsiveness and durability of the casing by combining an ultra-fine 290 tpi Corespan fabric with a durable, puncture-resistant belting and lightweight latex tube. And the silica rubber compound? It’s specially made just for the Tangente because, as it turns out, the gently scooped dimple patter is so much more crack resistant than grooved tread patterns, so we can use a lighter, better-gripping rubber with a lower rolling resistance than any other tire on the market. All without sacrificing a bit of durability. The new Tangente tire. Faster. Tougher. Stronger. Just like you.
