The design includes a tightly packed, fast-rolling center for straight-line control and speed, open transition knobs for sandy or wet terrain, and more aggressive shoulder knobs for controlled cornering and stability in loose conditions.

Top-level construction, materials and responsiveness for a solid foundation to build on. Designed to balance multi condition grip and robust durability, Eagle sport delivers great day-in, day-out performance in an economical package.
