Bombtrack Hook EXT Ti Titanium Gravel Bike

The Bombtrack Hook EXT Ti is built from 3Al-2.5V titanium, a frame material that resists fatigue and corrosion, shrugs off strap rub from bikepacking bags and keeps its finish for decades. Shimano's GRX Di2 RX815 groupset handles shifting and braking with a 48/31T crankset and an 11-34T Ultegra cassette, while a Seido MGV carbon fork and WTB EZR rims with 27.5 x 2.0" Ranger tyres give the clearance and grip for rough backcountry riding. A UDH derailleur hanger keeps future drivetrain options open. For New Zealand riders this is a long-haul adventure bike built to outlast the routes you buy it for.

Who Is the Bombtrack Hook EXT Ti For?

This is for the rider building a last bike rather than a next bike. Titanium does not rust, does not need paint protection where bags rub, and keeps the ride quality that makes long days bearable, which matters when a frame is expected to see a decade of gravel seasons rather than a couple.

Di2 shifting stays accurate when cables would be full of grit, and the 48/31T crankset with an 11-34T cassette covers both fast gravel and loaded climbing on New Zealand's steeper backcountry roads. The 2.0" Ranger tyres and 180 mm front rotor keep it composed well beyond formed gravel, and the full mount set supports lowrider racks, mudguards and dynamo lighting for extended trips.
