The square-lugged open tread pattern offers stability in loose or wet terrain, while the stiff outside knobs grip at lean angles like nobody&';s business. With Dual DNA rubber or Gravity DNA options, this is the tire to ride when you are giving it your all. TCS Light Fast-Rolling: Lightweight 60tpi casing with folding TCS aramid bead and Dual Compound DNA rubber (60a center/50a sides) Manufacturer Part Number: W010-0537
