700c, 27-Inch & 650c

Some of the greatest roads in cycling aren’t particularly well paved. Sometimes, the fact that they aren’t manicured like a golf green is part of the charm. Or maybe all of it. Today’s bikes, handlebars and other components are stiffer than ever, but the emergence of disc brake technology has created an opportunity for riders to run a high-performance 28mm clincher. The Speed R28 is chance to double down on traction, trim rolling resistance, improve your comfort on long days and even better your bike’s aerodynamics. Zipp has introduced the Speed R28 to give riders a race-ready tire for those days when you want all the performance of a top-of-the-line racing clincher at a pavé-swallowing width. Wet or dry, it combines the grip of a bigger contact patch plus the reduced rolling resistance that comes with a larger casing. - High-performance race tire - 28mm width - 220 tpi nylon casing - 216 grams - 21.97 watts of rolling resistance at 40kph (with Zipp butyl tube) - 60 ShA durometer rubber (Shore A) - New water-siping tread pattern - Supple over rough roads

Conventional wisdom on bicycle tires has held that smaller is better. Smaller tires were supposed to be lighter, more aerodynamic and have lower rolling resistance. Then came science. Research has shown that a larger tire has the ability to cut rolling resistance, making you faster than you would be with a traditional 23c-wide racing tire. And of course, a larger tire offers improved grip in dry and wet conditions. In some cases, when using the right rim, a bigger tire also can improve aerodynamics. Let’s not forget that comfort gets a big upgrade as well. The Zipp Tangente Course R30 tire give riders a high performance clincher at widths suitable for less than perfect conditions—rough roads, wet roads. The looming disc brake revolution will mean that you can run tires significantly larger than the 25mm limit on many bikes. The Tangente Course R30 tires take disc brakes’ opportunity for increased tire width and multiplies that with faster rolling, better grip and improved aerodynamics. - High-performance sport and training clincher tire - 30mm width - 120tpi nylon casing - Nylon puncture protection layer under tread - 260 grams (R28), 306 grams (R30) - 33.15 watts of rolling resistance @ 40kph (with Zipp butyl tube) - 70 ShA durometer rubber (Shore A) - New water-siping tread pattern - Comfortable in rough conditions

Every watt, every bit of energy counts whether you're racing or training; make sure you're getting the biggest aero advantage with Zipp's Tangente Course Tire. It takes advantage of Firecrest technology to reduce rolling resistance and increase airflow over the leading edge of the tire, meaning you work less to go faster. The rubber used in the Tangente tire is formulated for grip and acceleration, particularly in dry conditions, and the 120 TPI casing features a nylon puncture protection strip so you get as many miles as possible out of this rugged tire. It's light too, complementing your already feathery race day rig.

Zipp's Tangente Speed tires are a part of an aero wheel system that keeps you going fast, sticking in corners, and accelerating through the sprints. More than just a strip of rubber, the Tangente Speeds are optimized for smooth airflow with an aero tread pattern and materials formulated for grip and acceleration. Low rolling resistance means you save power over the course of a long race, and the 220 TPI casing is tough enough to roll over the roughest roads.

Designed for race day, the Tangente Speed is optimized for aerodynamics, rolling resistance and road feel with clincher convenience. - Rubber formulated for grip and acceleration - 220 TPI nylon casing - New aero tread pattern - Intended use: racing - Very low rolling resistance to save power - Optimized for dry road conditions - Sidewalls designed for supple and compliant ride feel

When you roll up to the starting line, you know you've got an aero advantage if your wheels are wrapped in Zipp's Tangente SL Speed Tubular Tire. The 320 TPI cotton casing is tough enough to tackle the ugliest stretches of blacktop, while the puncture-resistant belt keeps you inflated and rolling through the finish line. Zipp focused on improving leading edge airflow to get you that aero advantage, and the low rolling resistance saves power so you go faster longer. They even formulated rubber specifically tailored for grip and acceleration you'll notice as you're sprinting for the line. Your tires link you to the pavement; make that link as efficient as possible with the Tangente.
