Bombtrack Audax Gravel Bike

The Audax gravel bike from Bombtrack is the right base for gravel adventures. The sturdy steel frame together with the carbon fork gives you a fast and smooth ride. Shimano 105 equipment won't let you down even uphill. In downhill and tricky situations, you'll stay in full control thanks to hydraulic disc brakes. With Ritchey attachments, tubeless-ready wheels and various braze-on eyelets for pannier racks, fenders/mudguards and panniers, the Audax is a true adventure bike without limits.
