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.

¹ Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore Bombtrack cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local Bombtrack dealer or a professional bike fitter and have them determine the needed size.
