NS Bikes Define AL 170 2 Enduro Mountain Bike, Raw

The Define AL 170 2 is the biggest bike in NS's Define range: essentially a downhill bike you can pedal back up the hill. A 29" front wheel rolls through rough ground, while a 27.5" rear tucks in to make room for 170mm of coil-sprung travel.

It's built around a tough hydroformed aluminium frame with double-pass welds, semi-internal cable routing that's easy to service, and big sealed pivot bearings.

Who it fits

Riders who spend their weekends at bike parks, uplift days and steep enduro trails, and want one bike that's happy doing all three. Available in Small and Medium; the full geometry is in the spec tab, or get in touch and we'll help you pick a size.
