HOOK EXT FRAMESET

 

HOOK EXT

So what does the EXT stand for? Well the truth is we can’t even remember any more, extreme, extended, extraordinary…take your pick. The important thing, is what the Hook EXT is. 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. The fork was then developed specifically for this bike, with a super wide crown offering massive tire clearance and a stiffer tapered steerer tube for more accurate handling.
