The Mainline is S&M's trail tyre. Available in wire bead only with a mid weight, high pressure casing. The 2.2 has a micro knurled surface on a directional tread designed to go on the rear. It features a centre tread with a V-notched edge for accelerating and a flat edge for braking. The 2.4 front size is a nod to the old 2.125 Comp III we grew up riding in the front. Additional angular raised sections on three rows of knobs help keep the larger Mainline in front!  Also available in 22".
