Aggressive, premium and unflappable... these words describe the Vigilante 2.3 shell, and the same goes for its wider 2.5/WTB VIGILANTE 2.6 x 29 TCS versions. Massive growth of the height and the surface of the sipes which are capable of biting deeper and dig in earlier at the beginning phases of cornering. Wider, higher and more aggressive in all cases... Vigilante 2.5 / 2.6.
