S&M Mainline 20 Inch Tyre

Tear it up on these grippy rings from S&M Bikes! 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.
