comp III 25th Anniversary Edition

The 25th Anniversary Edition is an updated tread design of the Original introduced to commemorate the 25-year anniversary of the Comp-III. Modifications were carefully designed so the new tread retains the soul of the original but updated for more modern riding conditions. Compared to the Original, the 25th Anniversary Edition incorporates lower profile and more tightly spaced knobs for faster rolling as well as greater tapered knobs for increased rigidity.
