The Grand Prix Attack is made specifically as a front tire to handle the steering and braking forces encountered up front. At a narrow width of 22mm, and a weight of 190 grams, sharp corners are a breeze and air resistance and weight are minimized. When ridden with its partner on the rear, the Grand Prix Force (sold separately), it's a combo that's hard to beat.

Front and rear tires have to do very different things, so why should they be the same? The front-specific Attack features a sticky tread compound that assures high-speed cornering confidence, while the 22mm width and 4-ply casing cheat the wind and the scale. Because the rear is responsible for driving you forward and it bears more weight than the front, the rear-specific Force uses a hard compound and a 5-ply, 23mm casing for extended life. Put the two together and you have an excellent balance of function, weight and tread life.
