Product Details

2018 Jamis Defcon 3

This is where the 27.5” wheel size really shines: on a 160mm travel all-mountain enduro machine. Utilizing our proven mp4 suspension for pedaling efficiency, with modern geometry and top-level suspension to tackle bigger hits and aggressive descents at higher speeds. This progressive suspension design delivers plush rear wheel traction while still resisting bottom out. Rear thru-axles, short chainstays and roomy front centers provide stiffness, quick cornering and playful handling. If you want to do it all, fast, this is the bike.
