Bombtrack Hook EXT 2024
The EXT is where the Hook really starts to lead you astray. Utilising Columbus Cromor double-butted steel tubing, a tapered headtube, internal routing for dynamo lighting, and with our signature number of frame mounts, the EXT is ready for anything. Rolling on aggressive 27.5 x 2.0’’ WTB Ranger tyres, this is one very capable and exciting bike when you turn off the tarmac and head onto the trail. Sram’s hydraulic Rival 1x groupset provides both the transmission and the braking duties, featuring an 11 – 42T cassette paired with a 40T direct mount chainring and Rival rear mech. New for 2024, we fitted a Seido MGV carbon fork offering triple cage and low rider mounts, internal dynamo cable routing, as well as huge clearance for muddy high volume tyres. Turn off the gravel and head into the backcountry for some true wilderness adventure riding.
