Perfect for all-mountain and enduro bikes, Specialized's Slaughter GRID 2Bliss Ready Tire rolls fast in a straight line and still bites hard for confident cornering. A low-profile center tread ensures low-rolling resistance and secure braking, while tall side knobs provide the grip needed for cornering traction. The dual-compound tread provides heaps of traction, and the reinforced GRID sidewall and casing wards off pinch flats when you're pinning. And, it's 2Bliss Ready so you can run lower tire pressures, yet laugh in the face of pinch flats. Paired with an aggressive front tire, the Slaughter makes an excellent rear tire.
