Jamis
Crosscountry
TRAIL X A2 is an alloy cross-country mountain bike (2024), from Jamis, part of the Trail family. This model is best for a wide range of riders thanks to its fit flexibility, with a balanced riding position, with a surface profile that is best for smoother trails and efficient rolling. The main strengths in the metrics are strong value-for-money versus many similar bikes, strong climbing friendliness for sustained uphill riding, and good fit flexibility for dialing in rider position. At the same time, relative to category specialists, the trade-off is a firmer ride feel than comfort-first options. Use MatchBikes.com to compare this bike with nearby cross-country options.
