Hook EXT-C Green

The Hook EXT-C is a rugged yet agile adventure bike; with fat treads for improved grip, and Hunt's Adventure Sport 650b tubeless-ready wheels that feature WTB Venture tyres, it'll take on backcountry routes with ease.

Plus, this show-stopping green colour is sure to turn heads. But that's not all; the Hook EXT-C also receives a revised geometry and a full-carbon EXT V2 fork with triple cage attachments and SRAM's XD cassette for a wide range of gears from 10-42t. It's no wonder this rocketship is a favourite among the Bombtrack crew.

The HOOK takes it all- ticked off some Central Otago classics on my HOOK EXT-C like the Nevis, Thompsons Track and Omarama Saddle. Loaded it up for overnight trips in the Canterbury foot hills and rode fun flowy single track with chunky 2.2 MTB tyres.
Now running some semi slick 700c for faster road/gravel rides.
Super fun bike for going fast and far.

Fast bike-packing tourer to super light all road weapon...

Whether it’s boujee gravel race whip or rugged adventure bike packing rig, the Hook EXT C flips between the two effortlessly. Throw your chunky 650bs and load her up for a multi-day adventure, or run your fastest deep dish 700c hoops for commuting all the way to race day! Personally, I just keep the 700cs on there all the time!

The endless mounting points make packing and accessorising easy as pie, and man does it ride well fully loaded. On a multi-week adventure through Europe and the UK earlier this year. The green Hook EXT C performed faultlessly. With over 10kgs of gear onboard it felt built for it…which of course…it is! If I was fortunate enough to be in any place longer than a day or two, I’d quickly strip the bags off the bike and go out hunting those elusive European passes, promptly flicking the switch from
fast bike-packing tourer to super light all-road weapon.

With its clean lines, modest design and great spec, the Hook EXT C will just keep on rolling k after k, country after country, mission after mission and smile after smile!

Oh and I almost forgot to mention…it’s also sexy as hell!

Green sparkly gravel weapon!

This thing charges! Super well mannered, sooo capable and a fantastic finish. Geometry-wise it's just bang on. Oh, and it's green a sparkly. Top marks.
