Built for aggressive enduro riding
NS Bikes Define 2 AL 155 29" feels stable and composed right from the first ride. The long wheelbase, high stack and slack 64° head angle help the bike stay calm when the trail gets steep, rough and fast.
The 29" wheels carry speed really well through rocks, roots and rough sections. The bike rolls smoothly through technical terrain and gives you more control when trails get faster and more demanding.
A 452 mm reach in size M creates a modern and centered riding position. It’s easier to push into corners, stay balanced on steep descents and keep the front wheel under control during heavy compressions or rough landings.
The 440 mm chainstay keeps a good balance between stability and responsiveness. The bike doesn’t feel sluggish when changing direction, but still stays calm and predictable at higher speeds or on fast bikepark lines.
155 mm of rear travel handles bigger impacts really well and helps maintain traction in rough terrain. The suspension stays active under braking and performs smoothly through fast sections filled with rocks and roots.
The Rock Shox Domain R fork with 170 mm travel stiffens up the front end and gives more confidence during aggressive riding. Even during hard hits and deep compressions, the bike stays stable and predictable.
Modern geometry for fast enduro riding
The slack 64° head angle gives more confidence on steep descents and improves stability at higher speeds. The long front center keeps the bike calmer through rough terrain and helps you stay more controlled in technical sections.
A 75.5° seat angle improves climbing position and helps keep weight over the front wheel on steeper climbs. Because of that, the bike still climbs surprisingly well for such an aggressive enduro setup.
The high stack also improves control on steep trails and gives a more natural riding position during aggressive descending.
Safety
When riding enduro, it’s worth using a helmet and protective gear. Even experienced riders regularly use protection while riding bikeparks and technical trails.
