The priority here is functionality. The Fast Trak LK 26x2 wire bead front and rear tires, a standard feature on the HRXC mountain bikes, help with this emphasis on functionality. These tires will perform well in a variety of environments. The specially designed A1 premium Aluminum frame, another feature shared by all the HRXC mountain bikes, ensures that this bike will be able to stand up to some punishment. The brakes of the HRXC Disc, which set it apart from the other HRXC mountain bikes, are Tektro IOX (mechanical disc w/ 6" rotor). You operate these brakes with the Tektro alloy 2 finger brake levers. There are color options available for the Specialized HRXC Disc.
