NS Define AL 155 1 - The Do-It-All Machine
With over 150mm of travel in the rear and a 160mm fork this alloy 29er can blast through the rough stuff, while feeling great on a wide range of trails. This MTB can pedal up the sections that others have to walk and fly over sections that others have to plough through. The adjustable reach and BB height will let you dial the bike to your riding style and the trails you plan to ride. The frame’s unique semi-internal cable routing is a solution that is elegant and easy to service. Large, sealed pivots guarantee long periods of smooth, service free function.
