Buy the Continental Attack and Force tires as a set and save. The Continental Grand Prix Attack and Force tires with the Black Chili compound are specifically engineered to provide optimal performance as a front (Attack) and rear (Force) tire. Conti refers to theses front and rear specific designs as TPS - Tire Positioning System.
The front-specific 22mm Attack is designed for excellent grip and steering while the 24mm Force is constructed for higher mileage and durability as well as pure power transmission. Another noteworthy fact is that both tires are in the mid-180 gram range which bring the pair in at a feather light 374 grams. Although light, you can expect the same reliability as the Grand Prix 4000 series tires.
The amazing Black Chili tread compound is the highlight of the tires. It features tiny particles that conform to the road enhancing traction. It also makes the tread durable and last far longer than most competitors tires. Both tires have Vectran puncture protection strips inserted under the tread. It is essentially a protective belt made of super strong and extremely lightweight material. Small wear levels indicators have been molded into the tread to measure wear.
