ALMA M20
Orbea
Crosscountry
ALMA M20 is a carbon cross-country mountain bike (2024), by Orbea, from the Alma lineup. It suits riders looking for a balanced off-road setup, leaning toward a balanced riding position, with a surface profile that is best for smoother trails and efficient rolling. Standout strengths from the metrics include balanced, versatile speed for everyday riding, a balanced ride feel between comfort and directness, and all-round climbing capability rather than a narrow specialty. That said, compared with more specialized alternatives, the compromise is a value score that depends more on priorities than pure price efficiency.
