NS Bikes Define AL 155 2 2025 Bike

With over 150mm of travel in the rear and a 160mm fork this alloy 29er can can blast through the roughest stuff, while feeling great on a wide range of trails. This bike 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.

Adjustable Bottom Bracket Height

You can raise the BB height by 5mm from the stock settings by using the adjustable shock mount, or you can completely transform the bike by changing the shock mount & shock (changes travel from 155 mm to 130 mm or vice versa).

*Different lengths of shock mounts available separately.

Oversized Bearings, Sealed Main Pivot

The pivot that is most difficult to replace is hidden inside the frame and remains completely isolated from dirt and water inside the frame.

Hybrid Cable Routing

The cables appear to be threaded through the downtube and chainstay, but are actually only hidden in a special channel in the construction. Easy to replace anytime, anywhere!
