Commuting to work or school on black ice just got faster and easier with the Xerxes. 140 studs provide unrivaled control on those morning rides where ice patches threaten your commute. When a layer of snow conceals black ice, the ultra-narrow profile easily slices through the fluff and gets straight to business providing extreme traction in these extreme conditions. Run the Xerxes at minimum pressure for traction performance, and maximum pressure for a quieter and faster ride on clean roads. - 140 Steel Carbide Studs - Fast-rolling center tread - Narrow profile to fit in most 700c frames - We design 45NRTH tires for extreme winter cycling applications. We do not recommend this product be used with power assist bikes as the additional torque and system weight can lead to pre-mature casing wear and stud loss.

GRAVEL Cannonball is a go-to gravel race tire for normal conditions. The tread pattern features a directional, tight-knit center tread that sheds dirt and debris to decrease rolling resistance, and side knobs for effective cornering traction. Cannonball is built for all-around gravel riders and racers. HOW IT WORKS - Center lugs are raised and ramped for rolling efficiency; the diamond-shaped lugs squeeze in for grip as they contact dirt, then back out to shed debris. - Transitions lugs are spaced out and vary in height to boost traction. - L-shaped side lugs dig in for grip while braking through corners, but roll quickly when off the brakes.

Zipp's 303 S Tubeless Disc Brake wheelset provides today's cyclists the versatility they demand with the speed they crave. Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheelset maintains its ideal-for-every-terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. This wheelset is tubeless for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement. The 303 S is among our lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide. - Wide rims optimize tire profile to allow lower tire pressure, especially with tubeless. The result is a larger contact patch for increased grip and confident cornering, descending, and handling in wet conditions. - Lower tire pressures and larger volume provides a compliant ride with fewer vibrations. - Significant watt savings when running larger tires at lower pressure. - Wide, hookless rims create a seamless transition to the tire, reducing drag. - Fastest with 28mm, but fits wide gravel tires as well - New Zipp graphics and cosmetic identity that scream speed

Completely renewed, sporting a dynamic tread pattern design. Matches with a race bike, as well as a classic city road bike. Available in a wide range of dimensions and colors. PureGrip Compound Based on activated silica compounds, this technology was originally intended as an 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. Whilst 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). Suitable for E-Bikes For our E-Bike tyre 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.
