Technical specification

Technologies used

In this chapter we explain the technologies that the manufacturer uses for this product.

PureGrip Compound - The excellent compound technology

Based on the activated silica compound, a single-minded approach was taken towards a compound technology in the performance segment. The result Continental's research and development department in Korbach produced a new compound technology with excellent grip and cross-country skiing properties after intensive development efforts. The new rubber compound with the self-explanatory name "PureGrip" joins the BlackChili Compound and is used in performance products in the race and mountain bike segments. Here it ensures long-lasting traction and high mileage of Continental tires, which are manufactured exclusively in the production facility in Hefei (Asia).

PolyX Breaker - cut and puncture-proof
With the PolyX Breaker®, Continental brings car know-how to the bicycle tire segment: Polyester has been used successfully in car tires for years and has proven itself many times over. The extremely resistant polyester fiber is tightly woven crosswise. This achieves a very high tissue density, which not only makes the breaker resistant to foreign bodies, but also particularly resistant to punctures. The rolling resistance is also not negatively influenced by the PolyX Breaker®.

Plus Breaker - maximum security
A puncture protection made of highly elastic special rubber is used between the tread and the carcass. Almost impenetrable, this puncture protection successfully defies foreign bodies of all kinds. Even a thumbtack cannot penetrate it. The carcass is reliably protected from injuries. Tires with Plus Breaker can now be found in almost every segment: Whether racing bike, MTB or city / trekking, the Plus Breaker guarantees maximum safety without negatively affecting the driving characteristics of the tire. The consistency of the breaker has been adjusted so that the tire does not feel spongy when cornering. The Plus Breaker is pure puncture protection. Please note the air pressure information!

E50 - E-bike capable
For e-bike tires, Continental can draw on over 100 years of experience in moped and motorcycle tires. All city / trekking tires achieve at least the standard up to 25 km / h. The tires marked with E50 are also approved for S-Pedelecs. With their high-quality construction, they have a high level of puncture protection, low rolling resistance and protection against premature wear due to the additional driving force.
