PRIME RX
Mondraker
Crosscountry
PRIME RX is an alloy electric cross-country mountain bike (2023), from Mondraker, part of the Prime family. It suits a wide range of riders thanks to its fit flexibility, leaning toward a balanced riding position, while being best for smoother trails and efficient rolling. Its profile is strongest in areas like good fit flexibility for dialing in rider position, a balanced ride feel between comfort and directness, and capable suspension support for rougher terrain. At the same time, the main trade-off is less emphasis on outright speed than speed-focused builds. Compare this bike with other cross-country bikes on MatchBikes.com.
