With soft rubber compounds that stick to wet roots and rocks, as well as perfectly-spaced knobs that allow the tire to clean itself of mud and debris, the Storm Control 2Bliss Ready makes for a mud-munching tire that's made for riders who won't shy away from an environmental challenge. Or to put it another way, it delivers traction in sections that most riders won't even consider hiking over. 26 x 2.0"; psi 35-65; approximate weight 580g 29 x 1.8"; psi 25-50; approximate weight 545g 29 x 2.0"; psi 35-65; approximate weight 620g 650b x 2.0"; psi 25-50; approximate weight 600g Bead: Foldable Butyl wrapped bead = 2Bliss Ready Casing: 60 TPI for 15% improved cut-resistance Compound: 60a
