Mission Pro Frameset

The Mission Pro 27.5 frameset is a purpose built, no compromise All Mountain shred sled. Painstakingly constructed of weapons grade 6061-T6 aluminum alloy, the frame is designed to deliver punishment rather than take it. The oversized junction joining the tapered head tube, top tube, and down tube is a massive structure that will resist flex even when you’re landing the biggest hit, and the ultra stiff 142×12mm rear through axle construction will have you smashing corners. The FOX Float CTD Kashima equipped KnuckleBox suspension is beefy and provides the ideal balance of small bump compliance and big, bottomless feel which is only amplified by the 27.5” wheel platform that adds an extra degree of virtual suspension.


  • Hand built All Mountain 160mm travel 6061-T6 weapons grade aluminum frame with FSA headset is super strong and designed to take abuse
  • KnuckleBox suspension design with FOX Float X Kashima shock soaks up high frequency and square edged hits
  • Single-sided hardware on three main pivot points make bearing service a breeze
  • Oversized tapered head tube, top tube, and down tube junction coupled with 142x12mm rear through axle structure for nearly flex-free handling under load
  • RockShox Reverb Stealth post included
