Define AL 170 1
NS
Enduro
Define AL 170 1 is an alloy enduro mountain bike (2024), from NS, part of the Define family. This setup will suit a wide range of riders thanks to its fit flexibility, with a balanced riding position, while being aimed at more technical trails and rougher terrain. The main strengths in the metrics are capable suspension support for rougher terrain, a comfort-leaning ride feel over longer rides, and good fit flexibility for dialing in rider position. Relative to category specialists, the trade-off is less emphasis on outright speed than speed-focused builds. Compare this bike with other enduro bikes on MatchBikes.com.
