As a brand-new model for 2018 the Hook EXT-C builds on the success of the original model but in a full carbon fiber format. As with any Bombtrack the EXT-C is built to be versatile, allowing you the option for sticking on the smooth stuff or heading well off the beaten track. With any new model we are always keen to test each aspect of the bikes design and build to the fullest, in the case of the EXT-C the proving ground was the HT550 in the Scottish Highlands, possibly the toughest terrain a gravel bike is likely to ever encounter.

The frame features an optimised chainstay profile and seat tube scoop, designed to allow for larger tires (27.5 x 2.2" / 700 x 52c) and a shorter rear end for more agile handling. This solid and reliable SRAM Rival-1 drivetrain in combination with the Hunt Adventure wheelset ensure the Hook keeps going when the going gets tough.
