The Mainlines are our trail tires but they also make durable street tires. Available with wire beaded mid-weight, high pressure casings. The 2.10 (2.2 inflated) has a micro knurled surface on a directional tread designed to go on the rear. It also features a center tread with a V-notched edge for accelerating and a flat edge for braking. The 2.40 size is designed specifically as a front tire. Additional angular raised center tread sections keep the larger, front specific Mainline on the blue groove in turns!Available in 20 and 22 sizes.
