Eccentric Alu 29
NS
Trail
Eccentric Alu 29 is an alloy trail mountain bike (2024), by NS, in the Eccentric series. This bike is aimed at a wide range of riders thanks to its fit flexibility, with a setup that gives you a balanced riding position, with a surface profile that is well suited to natural trails and mixed off-road terrain. Based on the metrics, key strengths are strong climbing friendliness for sustained uphill riding, good fit flexibility for dialing in rider position, and capable suspension support for rougher terrain. That said, the trade-off to keep in mind is a firmer ride feel than comfort-first options and less emphasis on outright speed than speed-focused builds.
