Specialized Ground Control Control 2BR Tire

The Ground Control tire, with our new CONTROL casing, delivers plenty of versatility and flat protection. Not only does it feature improved cut-resistance, but we've also optimized the tread using Finite Element Analysis. It also features our own GRIPTON® compound that maximizes mechanical grip, damps vibration, and offers unparalleled traction in either wet or dry conditions.     Casing: 60 TPI    Bead: Foldable    Butyl wrapped bead = 2Bliss Ready    Compound: GRIPTON®    26 x 2.1", psi 25-50, approximate weight580g    26 x 2.3", psi 25-50, approximate weight 620g    27.5 x 2.3", psi 25-50, approximate weight 670g    29 x 2.1", psi 25-50, approximate weight 640g    29 x 2.3", psi 25-50, approximate weight 740g
