HOOK EXT C
The Hook EXT C comes complete with a carbon frame and V2 carbon fork with triple cage mounts for speedier off-road raids. Sram provide the bike’s 10 – 42T XD cassette for a great range of gears, so you can keep the pace high over whichever surface you decide to tear across. Our friends at Hunt handle the hoops, providing the bike with a tubeless-ready Adventure Sport 27.5’’ wheelset. Finished with head-turning tan-wall WTB Venture tyres, onlookers will have to be quick if they want to catch a glimpse as you fly through the undergrowth. It comes in this year’s glossy metallic black colourway, too.
With the ability to carry serious loads, triple mounts on the forks and three separate bottle cage fixings allow you to carry as much as you need with you.

¹ Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore BOMBTRACK cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local BOMBTRACK dealer or a professional bike fitter and have them determine the needed size.
