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.

With sizes ranging from a svelte 41mm all the way up to a hefty 4.8”, there’s a Knard to solve all your fast-rolling needs. - Folding bead - Casing: 60 TPI - Max pressure: 75psi - Weight: 660g

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

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.

From Rural to Urban The energy-saving SUV allrounder that gets you to both Rural and Urban. The partner for your commute, running errands and the weekend tour. PureGrip Compound Based on activated silica compounds, this technology was originally intended as a performance-level compound, but after intensive development at our Korbach Research and Development Department Facility, an advanced new compound with outstanding grip and cross-country properties was developed. This new rubber mix, given the self-explanatory name "PureGrip", is ranked just behind our BlackChili Compound and is being used in our performance products both in the road and mountain bike sectors. While providing great grip, it is also long lasting and highly durable—both characteristics of Continental tires, which are exclusively manufactured in the factory in Hefei (Asia). Shieldwall system The ShieldWall system combines the optimum combination of high puncture protection and the low rolling resistance with low weight. This is made possible by an additional, all-round puncture protection layer, which consists of a finely woven cross fabric. This gives the tire a high resistance to punctures and damage. Despite its additional ply, the tire has a very good damping property and a high degree of flexibility to adapt perfectly to the ground. The revolutionary tubeless ready bead allows easy and uncomplicated mounting of the tire. For best results in sealing and in use, we recommend the use of the new Continental RevoSealant sealant. Tubeless Ready Developed especially for the mountain bike sector, this additional puncture-protection layer which completely encircles both tire beads makes our carcasses robust and impervious against damage and penetration from foreign objects. For maximum effect we combine ProTection with BlackChili Compound. The result: versatile, low weight and an attractive design. In addition, tires made using this technology can also be used as Tubeless Ready. Suitable for E-Bikes For our E-Bike tire we fall back on over 100 years' experience with moped and motorcycle tires. All of our city/trekking tires are rated to a standard speed of at least 25 km/h. Those tires marked e50 are also certified for S-Pedelecs. With their high-quality structure, puncture protection is high and the rolling resistance is low, offering protection from premature wear brought about by the additional driving force.

T-Serv ProTite is a great performance tire for urban city use, incorporating ZSG compound, 400D Lite Extra Cord, and ProTite puncture-resistant technologies.

The ideal choice for fixed gears, single speeds, and urban bikes, the Grand Prix Urban combines a modern profile design with the latest technology.

With Continental's unique and legendary BlackChili tread compound, produced only in Germany, they have revolutionized the sport of cycling. This compound answers the eternal question of the best balance of grip and rolling resistance for cycling. Regular test wins confirm the measurable and noticeable advantages for cyclists, established in the lab and on the road. The latest polymers, as well as specially developed carbon black particles and filler materials, guarantee ultimate performance. This tire also offers superior puncture resistance with PolyX Breaker technology, using an extremely resistant polyester fiber in a tightly woven crosswise pattern. The result is a very high fabric density, which makes the Breaker more resistant to foreign objects and especially resistant to punctures, while not affecting rolling resistance.
