The Ground Control GRID 2Bliss Ready tire is an exceptionally versatile trail tire. CAD engineered knob shapes strengthen the knob structure for optimal braking and traction, but knob surfaces remain adaptable for the best possible ground control. Meanwhile, our proprietary GRIPTON® compound helps make this the perfect choice for epic trail rides in any condition. Please note that we recommend GRID tires for anyone seeking increased flat and sidewall protection, or additional stability.
