BOMBTRACK HOOK EXT

Bombtrack Hook EXT

The Hook EXT is Bombtrack’s  best selling bike for good reason.  Quite apart from its beautiful and hard wearing anodized paint finish, the Hook EXT ticks every box that a hard-riding gravel rider could wish for.  A premium quality steel frame, paired with a beautifully designed carbon fork delivers the optimum blend of stiffness, strength, reliability and low weight.  Featuring a full set of luggage bosses and huge tyre clearance the Hook EXT is ready to charge through the most extreme of gravel adventures.

“Bombtrack have another hit on their hands with the Hook EXT. It breezes through road sections, climbs and descends rough trails without breaking a sweat and well, just look at it! If you want a fast, smart looking bike that’s ready for taking on the rough stuff, you could do an awful lot worse than the Hook EXT.”  ADVNTR.CC

New 2021 Grey Blue Colourway

The Hook EXT has been updated with smaller wheels and wider tyres (allowing for tyres up to 52mm with 650b rims), but is still just as rewarding when set up with bigger wheels when you want to ride fast over less extreme terrain.  The bottom bracket has also been widened to a more durable T47 bottom bracket and cable routing has been revise to keep the bike looking clean with any combination of derailleurs, dynamo wiring and dropper posts. Frameset upgrades for 2021 include a new more compliant tapered headtube, and internal cable routing for a rear light, which feeds a newly added light mount.

The Hook EXT frame is built from premium Columbus Cromor tubing, with a tapered head tube, through axles, and rack and fender mounts.  For those looking for luggage carrying capacity the Hook EXT has it covered – top tube bag direct mounts, triple cage mount on down tube and seat tube for optimized bottle position, bottle cage mounts underneath the down tube, with a full carbon tapered fork featuring internal light cable routing, through axles and triple cage mounts.

“Go anywhere gravel – why the Bombtrack Hook EXT is a blast:  There’s something about the Hook EXT that encourages you to ride more and more technical terrain. The high volume tyres allow you to move over rougher ground with a confidence and comfort that you simply don’t get with 40c. As spring gave way to summer and the trails became hard packed, that added cush genuinely made a measurable difference when it came to speed. As unintended and unscientific proof, Strava found the Hook EXT quicker on flat but rough tracks than lighter 700c-wheeled gravel bikes.” GritCX

“More efficient than a mountain bike, more rugged than the typical gravel bike, the Hook EXT is spectacular fun. Bombtrack has somehow created a bike this is both nimble and playful as well as stable and a safe pair of hands on quick descents. It spans genres, while managing to be really damn good at each, rather than the classic “Jack of all trades”. ” Singletrack Magazine
