“Nomen est omen” JACK the GRIPPER with the dimension 140/80-18 he is no less than his name and offers a bloody lot of grip. A more stable sidewall provides first-class lateral guidance. The No-Bounce rubber compound allows maximum GRIP in streambed and on wet stones.
The arrangement of the knobs in V-shape and with a height of 14.3 mm ensures extreme forward propulsion in boulders and deep ground. Of course, it is available in three different hardness/rubber compounds HARD, MEDIUM and SOFT.
