BOMBTRACK HOOK EXT-C

Bombtrack Hook EXT-C

The Bombtrack HOOK EXT-C is outrageously responsive while at the same time being equipped for anything you or the trail can throw at it. When you want to go wild places fast, there simply isn’t a better bike for the job.

2021 Gloss Dark Green colourway

An ultralight carbon frame strips mass from its best-selling stablemate, the Hook EXT, while retaining the versatility the range is known for, with capacity for huge tyres and a perfectly balanced geometry. Triple mounts on the forks, mounts on the top tube, bosses everywhere and three separate bottle cage fixings allow you to carry as much as you need with you.  Frameset upgrades for 2021 include a new more compliant tapered headtube, greater chainring clearance and internal dynamo cable routing.

If someone stopped me today and said “I want a gravel bike for £3k that’ll do everything, what should I buy?”, The Bombtrack Hook-EXT-C would be the first bike to spring to mind. ADVNTR.CC

The Bombtrack Hook EXT-C is available either as a factory built bike with 650B Hunt Adventure Sport wheels, easy rolling WTB Ranger tyres and a SRAM Rival 1x groupset, or (more commonly) as a frameset for custom builds, using either 1x or 2x groupsets and 700c or 650b wheels. The choice is yours – load it up and take on challenging terrain with tyres up to 2″ wide, or slim down to 45mm gravel tyres on 700c wheels and race the Dirty Reiver. In any scenario the Hook EXT-C represents the endpoint of Bombtrack’s speed focused gravel line.

Whether you are looking to ride quickly over varied terrain or to kick back and explore the world off the beaten track, or mix in a bit of everything the real world can throw at you, the Hook EXT-C has you covered.  The classy under stated finish is extremely robust, while frame and fork strength and reliability are exactly what you’d expect from Bombtrack, a global leader in adventure and gravel riding.

We love the no compromise versatility this bike – if you are looking to ride hard the Hook EXT-C will respond to your every pedal stroke, and offers a perfect blend of off-road loaded stability and razor sharp handling, while the sophisticated carbon fibre layup paired with large volume tyres means it is equally at home when you are feeling more laid back.

As well as the Bombtrack factory built full bike, we are also able to offer a full custom specification with the Hook EXT-C – which is the route that most of our customers take as it also represent outstanding value for money.  Starting with a bare frameset we can build you a full bike using components of your choice (see below for some examples).
