Hook EXT TI is made from 3Al-2.5V Titanium, the perfect material for a gravel bike. Titanium withstands fatigue like nothing else and won’t corrode. It is lightweight, and doesn’t scratch when you strap bags to it, plus it has that special responsive zing when you push hard on the pedals. Shimano’s GRX Di2 815 groupset is the ideal match, providing punchy braking and top level transmission performance through a 48 / 31T chainset and an 11 - 34T cassette. WTB EZR rims with 27.5 x 2.0’’ Ranger tyres deliver confidence through their all-terrain grip.  
Both Seido’s MGV fork and the Hook EXT TI frame bristle with an array of mounting options – a signature feature of our brand’s essence. Load up, just ride.
