Process 153 27.5
Kona
Enduro
Process 153 27.5 is an alloy enduro mountain bike (2024), by Kona, in the Process series. It suits a wide range of riders thanks to its fit flexibility, leaning toward a balanced riding position, while being aimed at more technical trails and rougher terrain. The main strengths in the metrics are strong value-for-money versus many similar bikes, strong climbing friendliness for sustained uphill riding, and capable suspension support for rougher terrain. The main limitation versus more focused builds is a firmer ride feel than comfort-first options and less emphasis on outright speed than speed-focused builds.
