The Kenda Karma 29er Kevlar Tire features DTC Compound which has Kenda's L3R Pro (hard) compound in the center of the tread for speed and long life. Kenda's Stick-E rubber on the transition and cornering knobs provides better grip in turns. The small square knobs on the Kenda Karma 29er Kevlar Tire accentuate this tread pattern for fast XC rides and races.
