A lightweight ALUXX aluminum frame, engineered with comfortable geometry for challenging terrain, adds to its rugged personality. It also uses size-specific wheel diameters�smaller size bikes use 26-inch wheels, while larger sizes use 27.5. This tailors the bike�s handling to every rider�s size and height.
