Hook EXT Apex Eagle
"Gravel racing is such a varied discipline, with courses spanning from 100km to Ultra Endurance distances - the Hook EXT is there for any competitive scenario"
Bombtrack Hook EXT Apex Eagle
This bike’s built tough with Columbus Cromor steel tubing, giving it a smooth ride and loads of durability. We’ve loaded it up with all the mounts you’ll need to carry your gear: racks, cages, whatever you want. The WTB Ranger 27.5 x 2.0” tires grip the trail like a champ, making it a blast when you leave the pavement behind. Thanks to the SRAM Apex Eagle 1x setup, shifting and braking feel solid and simple, with a wide gear range to tackle anything from steep climbs to fast flats. The Seido MGV carbon fork also has plenty of mounts and room for big tires, plus neat hidden cables to keep things looking clean. Basically, the EXT is ready to roll wherever your ride takes you, whether it’s a quick spin around the neighbourhood or a weekend off-road mission.
