The Edge is designed to perform in intermediate conditions. Especially effective when open terrain is dry and the woods are wet, this tire was designed for extra compliance on slippery wet rooted rocky trails. Multiple notched knobs all over the tire provide a soft feel with tons of "Edges" that bite into intermediate soil and give this tire its name. Ramped center knobs lower rolling resistance and add knob stability under hard braking. The new 2 ply foldable tire will save you over 295 grams per tire while keeping you on route with the S 50 Sticky Rubber Compound.
