Arctodus 1×12 SRAM GX Eagle
Otso
Fatbike
Arctodus 1×12 SRAM GX Eagle is a steel fatbike mountain bike (2024), by Otso, from the Arctodus lineup. It is best suited to riders looking for a balanced off-road setup, with a setup that gives you a balanced riding position, with a surface profile that is useful on softer and looser terrain. The main strengths in the metrics are strong climbing friendliness for sustained uphill riding and a comfort-leaning ride feel over longer rides. The main limitation versus more focused builds is less emphasis on outright speed than speed-focused builds and a value score that depends more on priorities than pure price efficiency.
