Kenda's Karma has been a favorite of XC riders and racers for years and has numerous NORBA wins to back it up. Small, square knobs accentuate the tread pattern for fast rides. And, the tubeless compatibility offers a distinct advantage over conventional tires in ride quality and flat resistance. Because there is no tube, the tire can be run with approximately 10-15% less air pressure than conventional tires. The result is improved traction in rough conditions and elimination of pinch flats.
