Troy ST GX AXS 12s
Devinci
Trail
Troy ST GX AXS 12s is an alloy trail mountain bike (2025), from Devinci, part of the Troy family. This model is best for riders who want a more active, performance-leaning off-road feel, leaning toward a sporty, active riding position, with a surface profile that is well suited to natural trails and mixed off-road terrain. Its profile is strongest in areas like strong climbing friendliness for sustained uphill riding, a balanced ride feel between comfort and directness, and strong speed potential on smoother terrain. The trade-off to keep in mind is a value score that depends more on priorities than pure price efficiency.
