Introducing the Hook EXT
The Hook’s hoodlum tendencies given free rein. Using a Columbus steel frame, dedicated carbon fork, and lively 27.5-inch wheels, the EXT can batter through territory out-of-bounds to other drop handlebar bikes. Backed by Sram’s 1 x 11 Rival groupset, this provides both the gearing range and braking power needed for extreme riding. Adding more build options, this year sees the addition of an integrated rear light mount.
