FAULTLINE A2
Jamis
Trail
FAULTLINE A2 is an alloy trail mountain bike (2024), by Jamis, from the Faultline lineup. It suits a wide range of riders thanks to its fit flexibility, leaning toward a balanced riding position, with a surface profile that is well suited to natural trails and mixed off-road terrain. Its strongest points in the MatchBikes metrics are strong value-for-money versus many similar bikes, strong climbing friendliness for sustained uphill riding, and a balanced ride feel between comfort and directness. That said, the trade-off to keep in mind is less emphasis on outright speed than speed-focused builds.
