the Hook EXT
...takes 'road-plus' further off the beaten track and sets the benchmark for a steel gravel bike.
"CX/gravel geometry with clearance for bigger knobby mountain bike tires, something gravel racers have long dreamed of."
Introducing the Hook EXT
Smaller wheels, bigger tyres, rowdier personality. The burly Hook EXT is made for the most extreme drop bar adventures. A classic case of "if it ain't broke – don't fix it!". Besides adding a wider, more durable T47 bottom bracket we've revised the cable routing to keep the bike looking clean with any combination of derailleurs and dropper posts. Besides this, the bike retains the same gorgeous matt metallic grey paint scheme and awesome parts list that’s made it a pin-up for many gravel nerds. Additional frame features include the invest cast chain stay yoke, dropper post compatibility and direct mounts for top tube 'fule tank' bag. This versatile frame 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 clearance for anything up to 45c tires.
Frame uses Bombtrack casted drive-side yoke, extra cage mount under down tube, direct mount top tube ‘fuel’ bag and stealth dropper post routing.
Columbus Cromor, double butted front triangle chosen for its lightweight yet durable properties ideal for CX and gravel rides.
Straight blade extra wide full carbon fork with triple cage mounts and 12mm thru-axle.
Clearance for 27.5 x 2.1" or 700 x 45c.
