Mason Pro

Are you ready to brave the All Mountain world without the luxury of full suspension? If you are, then the Mason Pro 29 is just what you’re looking for. This low slung, slacked out sled gives you just the right geometry for aggressive trail shredding and the weapons grade 6061-T6 aluminum alloy construction is plenty strong enough to take on the task. The tapered head tube and 142×12mm through axle rear dropouts stiffen up the handling front and back, while the formed and butted tubing shores up everything in between. Roll out the whole rig on 29” Stan’s wheels, a Fox 34 FLOAT 29 CTD air fork and a RACEFACE Respond crankset with Narrow-Wide Single Ring and you’ll be heading to the trails every chance you get.


  • Hand built 6061-T6 weapons grade aluminum hardtail frame w/ slack, low slung geometry is ideal for All Mountain riding
  • Stan's ZTR tubeless 29" wheels
  • SRAM X9 10-speed drivetrain with RaceFace Respond crank and narrowwide ring delivers crisp, reliable function
  • FOX Float 29 CTD 140mm suspension fork with 34mm stanchions takes the big hits without flinching
  • KS Lev dropper post
