The Specialized Purgatory CONTROL 2Bliss Ready Black Tyre is the standard bearer for light trail tire performance. The new, completely redesigned tread features square lugs that bite in on soft soil, while still providing support on hard-packed ground. Additionally, flexible center sipes fold out under braking force for increased ground contact and adhesion. To top it all off, our proprietary GRIPTON® compound helps make this the perfect choice for epic trail rides in any condition.Specialized Purgatory CONTROL 2Bliss Ready Black Tyre FeaturesCasing: 60 TPIBead: FoldableButyl wrapped bead = 2Bliss ReadyCompound: GRIPTON®29 x 2.3, psi 25-50, approximate weight 750g\"
