HARDLINE C4
Jamis
Enduro
HARDLINE C4 is a carbon enduro mountain bike (2024), by Jamis, from the Hardline lineup. It is a strong match for riders who want a more active, performance-leaning off-road feel, leaning toward a sporty, active riding position, and is aimed at more technical trails and rougher terrain. Its profile is strongest in areas like strong climbing friendliness for sustained uphill riding and capable suspension support for rougher terrain. Relative to category specialists, the trade-off is a firmer ride feel than comfort-first options and less emphasis on outright speed than speed-focused builds.
