Mission 1

The Mission One is a bike that could not have existed just a couple years ago: a so-called “entry level” all-mountain bike that’s as capable and tough as bikes that cost thousands of dollars more. As our KnuckleBox suspension design has evolved, the bikes that use it have become better—at every level. The Mission One revolves around its tough-as-nails hydroformed aluminum frame with 160mm of Fox suspension travel front and rear. A wide range SRAM 1×10 drivetrain, Shimano hydraulic brakes (180mm rotors), and a tubeless-ready setup—what’s not to love? It’s dropper-post ready, has a stiff 142×12mm thru-axle rear end, and just plain rips trails apart. If you’re looking to enter the waters of go-anywhere, do-everything full suspension quiver killers, the Mission One is the starting point.


  • All Mountain 160mm travel 6061-T6 aluminum frame with KnuckleBox suspension is super stiff and ultra durable
  • Single-sided hardware on three main pivot points for easy bearing serviceability
  • FOX 34 Float CTD air front and CTD "LV" rear suspension will smooth out any trail
  • SRAM X7 type 2.1 rear derailleur delivers silent, accurate shifting
  • Race Face Ride 30t NarrowWide 1x Crankset is practical and efficient
