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 R28 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 R28 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 - 28mm 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

When you’re out on a ride the last thing you want is to be limited by your tires in any way. Our ExtraTerrestrial Tires were designed to let you ride without limits by simply following the only tenets we have for tire design: they’re high volume and they kick ass. The ExtraTerrestrial tire was meant to serve as a heavy-duty off-road touring tire that shines on hardpack surfaces. It uses a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread to protect against flats. The ET Tire uses a distinctly directional tread pattern and its width yields more traction than you might expect from a tire with such little rolling resistance. The tread is low profile with a file tread in between tread blocks. The ExtraTerrestrial tire has enough width and traction for the soft stuff and won’t bog you down on smooth or hard surfaces. - Folding bead - Casing: 60 TPI

The Knard is a tire that just makes sense. With its tightly-spaced, low-block tread pattern, it provides the perfect ratio of traction and low rolling resistance.

Jobst Brandt was an important figure in Tom Ritchey's life. Along with Tom's father, who was also a cyclist, Jobst was an important mentor for Tom - faithfully sharing his vast engineering wisdom while also actively influencing Tom's riding. Bound only to the thrill of experience and exploration, for decades Jobst's and Tom's tires rode over more than a few different surfaces on any given ride. It's these adventures with Jobst that helped inspire the Alpine JB tire. This unique bicycle tire is built to ride wherever your two-wheeled journeys may take you. It rolls beautifully on all-day rides along smooth country roads, yet it has enough tread to gracefully navigate roads with minimal municipal maintenance or long stretches of gritty gravel. The Alpine JB enjoys a 120 TPI casing, is tubeless-ready and employs the unique VFA tread design - a pattern that's mostly recessed in the rubber of the tire, rather than relying on protruding knobs more commonly found on such tires. Thanks to the inverse tread, rolling resistance is smoother compared to traditional knobby tires, yet grip and confidence remain inherent features. An added benefit is that the Alpine JB is more durable because there are no knobs to wear down. - Tubeless-ready (only 35c) - VFA tread design - Stronghold Casing - 120 TPI

The big news from Donnelly is the upcoming EMP gravel tire, which pulls its name from the airport code for Emporia, Kansas, home of a kinda popular gravel race that crushes souls every year. The tire is a departure from their usual tread design, getting a tighter tread block pattern without a well-defined center strip like most all of their other tires. It’s still designed to roll fast, which is key if you’re racing any long distance gravel bike event, but with bigger side knobs to handle more aggressive cornering. - Smooth-rolling center knobs and aggressive shoulder lugs - Soft rubber compound for extra grip and shock absorption - Integrated puncture protection belt under the tread - Tire Intended Use: Gravel - Labeled Size: 700 x 45 - Tire Bead: Folding - Tire Diameter: 700c - Tire Type: Clincher - Weight (oz): 21.7 - TPI: 60 - Flat Protection: Tread

The Strada is Challenge's go-to tire for long days on the road. This all-condition tire combines a round profile that takes the sting out of rough pavement with a construction that provides maximum control and low rolling resistance. This TLR clincher with 120TPI nylon casing provides both performance, durability, and puncture protection when combined with the appropriate tubeless sealant. TLR - TLR tires versions can be ridden tubeless with the addition of sealant but can also be run with an inner tube. - A bead-to-bead inner coating gives added puncture protection to these tubeless ready tires and greatly reduces gradual loss of air pressure. An aramid bead protection strip increases tire longevity and reduces rim chafing.

The e-bike specific version of our popular city and touring tire maximizes range and extends battery life while delivering the dependable performance you expect. Reflective sidewall stripe increases your visibility for oncoming motorists, while the reinforced casing eliminates punctures. - Hard-working, hard-wearing tire built for racking up big mileage - The ideal tire for city riding and touring, even in semi-wet conditions - Graphene 2.0 compound reduces rolling resistance, increasing range and battery life

An energetic cosmopolitan! Tires are a safety-relevant component of each bicycle. High speeds and the additional weight from the battery and drive of an e-bike of up to 50km/h make a special e-bike tire necessary. A high-quality additional rubber 3/180 TPI reinforced carcass forms the solid frame of the E.CONTACT. The SafetyPLUS Breaker puncture protection specially developed for the high demands on e-bikes, protects the tire reliably against punctures and cuts. The profile of the tire is just as at home on asphalt as on gravel and forest trails – a good all-around tire.
