Continental Grand Prix Attack-Force Road Tire Set
For Continental, Grand Prix series tire development derives from experience in every category- auto, moto, bike, speciality. While delivering tires at the top end of racing competition, particularly in Moto GP, the engineers decided that with the proper considerations, the front/rear specific width and tread combinations used on the motorcycle track could be applied to competition road bike tires. The Grand Prix Attack and Force tires are specifically engineered to provide optimal performance as a front (Attack) and rear (Force) tire combination and Conti refers to these front and rear specific designs as TPS - Tire Positioning System. Ideally these are racing clinchers, best used in in events from criterium through time-trial, and triathlon.
The front-specific 23mm Attack is designed for aerodynamics, excellent grip, and steering, while the 25mm Force is constructed for greater wear and durability, as well as pure power transmission. The tread patterns and rubber thickness are specific to each tire, with the Attack requiring less rubber due to the fact that a high percentage of rider weight is carried by the rear tire. Both tires are directional, and the tread pattern was optimized for the differing loads and needs of each tire.
The amazing BlackChili tread compound is what makes the complex design truly shine. It features nano-particles that conform to the road enhancing traction and it was optimized for the function of each tire. The compounded properties deliver excellent wear, and as little rolling resistance as possible in a racing clincher that is more than capable of holding in a 45mph corner. Both Attack and Force tires have a single layer Vectran puncture protection strip inserted under the tread for flat protection. Vectran is essentially a protective belt made of super strong and extremely lightweight material. Carrying all this technology is Conti's proven 3 ply/330 tpi casing, which offers great feel and control. The recommended tire pressure range is 110-120 psi.
These tires were designed to be firm, which maximizes the design and rubber compound's capabilities. After taking a few practice corners at speed, you will appreciate this, and realize how much faster you will be able to enter and exit with. Small wear level indicators have been molded into the tread help you monitor tire life. Buying the set saves you money on a terrific lightweight set of racing clinchers, and you can be confident that Continental has provided you with the Force to Attack in all situations.
