DESCRIPTION:

Introducing the Hook EXT

Built on a 27.5” rim and using a wider tire produces a wheel with the same outer diameter as a typical 700x28c. This means it’s possible to run bigger knobby mountain bike tires, with all the grip they offer, yet retain the geometry of a CX/gravel bike, something gravel racers have long dreamed of. This is made possible thanks to a specially designed frame that utilizes a wider bottom bracket and yoke to maintain a wide yet short rear end. The Columbus Cromor double-butted tubing has the perfect blend of being lightweight yet durable, perfect for gravel riding. For 2018 the EXT features a new full carbon fork, with anything cage and fender mounts, creating more options for front end luggage. Additional frame features added for 2018 include the invest cast chain stay yoke, dropper post compatibility and direct mounts for top tube bag.

The SRAM Rival 1 is ideally suited to the Hook EXT, thanks to its simplified 1x design with clutch derailleur, wide range cassette and X-sync chainring providing smooth shifting in any conditions. The hydraulic brakes bring a superior stopping power to the EXT, which is reassuring on steeper technical descents. The versatile build is designed to offer as much all-round use as possible, so if your journey is mainly on-road, swap out the wheels for a set of 700c’s, with anything up to 45c tire.
