HOOK EXT C FRAMESET
A fast bike for all kinds of riding. The Hook EXT C might have been designed as a gravel racer, but that doesn’t stop it also being a perfect tourer, commuter, or even summer-season cyclocross bike. Offering uprated strength and manoeuvrability, this agile adventure bike is the perfect companion for technical backcountry raids.
An ultralight carbon construction strips mass from the Hook EXT while retaining the versatility the range is known for.
