First introduced in 2007, Zipp’s tires were initially focused primarily on aerodynamics, which led to some compromises in rolling resistance and handling. With the Tangente line, Zipp clearly went back to the drawing board with renewed attention toward creating balanced, fast-rolling tires with supple shoulder grip for confident cornering. The Tangente Speed Clincher Tire features exceptional traction in dry conditions, an aerodynamic profile, and low rolling resistance. Billed as a race-ready tire best suited for days when the weather is fair and the roads are dry, the Tangente Speed features a high, 220 TPI nylon casing for a supple ride and confident road feel. Zipp also incorporates a proprietary rubber compound for impeccable grip to rail corners and jump on the attack, and the company claims that the tread pattern is designed to optimize aerodynamics. We haven’t verified this claim, but we definitely welcome any feature that promises to help maintain a hard-earned gap when the line is still a ways off and our legs — like our options — are exhausted.

Intended for racing and training, optimized for dry road conditions. 120 TPI nylon casing with nylon puncture protection strip. New aero tread pattern.

It’s no surprise that top athletes like Chris McCormack – who has won at Kona on the Zipp Tangente – and the women of Team Exergy TWENTY12 are seeing the benefits of Tangente aero tires. After all, your tires have the highest airspeed of any part of your bike, and the front tire is your machine’s leading edge. It took us 14 months and two trips to the wind tunnel to get it right, resulting in the 21 mm version of the Tangente saving up to 9 seconds over 40 km compared with a traditional non-aero shaped tire when each was paired with a Zipp rim. The secret to the aero success of the Tangente line of tires is the shape. The leading edge radius has a slightly more pronounced point than a traditionally round-shaped tire, starting the airflow transition from tire to rim sooner and more efficiently. While also helping the Tangente cut through the wind, we’ve used our patented ABLC dimples to help the tire better adhere to any road surface more efficiently than a traditional “file” tread pattern, helping to deliver better cornering and braking. The dimples are not connected to one another, resulting in a lower overall stress in the tire casing and a smoother rolling and longer lasting tire. Tangente clincher racing tires come in 21 mm or 23 mm widths. Average weight 245 g, /- 10g (for clincher). Valve stems of 37 to 40 mm in length recommended for use with Zipp valve extenders. Packaging includes tire pressure chart to optimize rolling resistance by rider weight and front/rear use.

The Tangente is not just a delicate special event tire. Thanks to our partnership with Vittoria , the Tangente sports a durable yet supple 290 tpi casing. Because the dimpled pattern resists cracking so well, we’re able to use a lower durometer rubber compound resulting in low rolling resistance and high cornering grip in wet and dry conditions. Tangente tubular racing tires come in 21 mm or 23 mm widths. Average weight 282 g, /- 10g (tubular). Tangente has a 25 mm valve stem (valve stems of 37 to 40 mm recommended for use with Zipp valve extenders). Packaging includes tire pressure chart to optimize r
