HOOK EXT TI

 

The versatile Hook EXT TI distils the rough-and-ready yet comfortable nature of the Hook collection. Light and responsive, the titanium frame partners alongside a V2 carbon fork with triple cage mounts, as well as a multitude of luggage configurations for added cargo options. Fitted with Shimano’s latest electronic GRX Di2 groupset, a double crankset provides close-ratios but a wide range. Making tubeless set-up easy, its lightweight WTB EZR rims and fast rolling WTB Ranger TCS Light tyres provide excellent speed and traction across mixed conditions.

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.
