Some might say that full suspension is just a crutch for those who don’t have the guts to go hard charging on a hardtail. If you’re up for it, then so is the Mason 29. The weapons grade 6061-T6 aluminum frame is built tough, and with a low slung, slack geometry it’s plenty maneuverable to take on true All Mountain terrain. The formed and butted tubing balances strength with light weight, and the beefy tapered head tube and 142×12mm rear through axle construction lend some extra muscle for better handling. It all sounds pretty good so far, but add fast rolling, trail hugging 29” wheels a Rock Shox fork and a Race Face Narrowwide 1x setup and you won’t even miss those crutches.


  • Hand built 6061-T6 weapons grade aluminum hardtail frame w/ slack, low slung geometry is ideal for All Mountain riding
  • Rock Shox Sektor 29" fork offers 140mm of butter smooth travel
  • SRAM 10-speed drivetrain for durable performance
  • RaceFace cranks with narrowwide ring offers simplicity and light weight
  • DB AM290 29" wheels are fast rolling
