It has very high mileage and outstanding grip on wet streets and at low temperatures. Offered in 23 mm, 25 mm, and 28 mm, the Grand Prix 4 Season will ride any street at various comfort levels. Double Vectran™ Breakers increased puncture protection to above that of the best tyres on the market.

Technology:


Premium
Continental Premium tyres are made or the highest performance. They use the latest technologies developed with the world’s most successful athletes. The tyres are also handmade by experienced specialists in Korbach, Germany. Only the best materials is used for the highest quality and exceptional properties.

DuraSkin®
Tyres with DuraSkin® sidewall protection have to be able to roll with the punches. They are used under the harshest conditions. On messenger bikes, the tyres skid along curbs; on touring bikes, they cross continents without wearing out. In racing cycling, they have to endure tough tests such as the Paris-Roubaix. The high-quality polyamide fabric protects the tyre casing against the worst conditions. These tyres stand out thanks to their brown sidewalls.

Vectran™ Breaker
Vectran™ is a synthetically manufactured high-tech fiber from a natural model. Like spider silk, Vectran™ is a liquid-crystalline polymer [LCP]. Vectran™ is spun from the melted liquid polymer Vectra and processed further to a multi-strand thread. Spider silk like
Vectran™ has an enormous tear resistance at a very low weight.
How Vectran™ is used highlights its resistance: for astronauts, spinnaker sails, deep-sea cables, and cut resistant clothing. Vectran™ can be found everywhere where extreme durability is needed. Vectran™ threads have a tensile strength five times higher than steel and are fatigue resistant making them very resilient. Exactly the right properties to process into a premium Continental bicycle tyre as a puncture protection insert. A Vectran™ Breaker is lighter, more flexible and protects more effectively against cuts than the comparable nylon breaker. Vectran™ Breaker does not adversely affect the rolling resistance.

2017 modelmight come larger than expected!!!!
It's the third or fourth (rear) tyre that I fit (all 28mm) on my 28mm compliant frame, but this time it came wider than usual. I had to true my wheel to avoid rubbing against the frame. (this was on a workstand). Unfortunatelly, on the pavement, once applying power on the pedals or in some curves the tyre is still touching the frame (note; never had that issue before even with the former tyre which I changed because a "bulb" appeared after (8?) thousands km. Also my wheel was still ok needed about 1mm trueing. I have no tool to measure exactly how wide the tyre actually is, but a simple trick with an alen key and electrical tabe showed it. Also changing with the front tyre solved the problem instantly.
For a high end tyre of a major brand it's quite disapointing. On the other hand I ever had any other issue with this tyre and the rear always took at least 6000km.

Al na 300km is de band gescheurd in een naad. Hier laat zich het nadeel van een
buitenlandse Internetdealer merken. De band ken ik evt opsturen (verzendkosten voor eigen rekening) en dan maar afwachten of het onder de garantie valt. Dat is natuurlijk een behoorlijk nadeel. Ik kon de band niet rechtstreeks naar Continental Nederland sturen.

Bought for the winter but sadly surprised by a tear in the sidewall after one week usage :-(

Not the lightest, not the fastest, not the smoothest, not the most puncture proof - but it is close to all those features. It combines all of these important characteristics in a "charming" way. Living and biking in Denmark with lots of rain and flints your chose of tire is existential - I believe I have tried every serious tire (clincher/faltreifen) out there, 4-season comes out on top every time.

Fantastic year-round tires. Very durable with incredible grip. Fast during summer, secure and confident during winter and wet weather. Also, they look fantastic.

Durable enough for urban use and gravel paths, good grip, light weight. I wish they were available in plain black without the orange side strip, though.

A "must have" for Germany's cold wet autumn and spring. Get them in 25mm and they'll be sturdy enough for forestroads as well.
