Sortie 1 29"

The Sortie One 29 is a fabulous, free-spirited XC/Trail machine to explore any singletrack you can find. Built of weapons grade 6061-T6 aluminum alloy, the frame is light but strong enough to stand up to whatever you can throw at it. The 125mm of KnuckleBox suspension rounds off trail obstacles so you won’t get bounced around, and the tapered head tube and 142×12mm rear through axle add stiffness to help keep you on your line. Add on a Shimano drivetrain and brakes and an easy rolling 29” wheelset and there’s no second guessing that you’ve got the one bike you need.


  • Hand built 125mm full suspension 6061-T6 weapons grade aluminum frame is lightweight and durable
  • Specially formed and butted tubes, and under arch seat stay bridge optimize strength to weight
  • KnuckleBox Technology and FOX Float CTD suspension round off trail impacts
  • Fox Float CTD 29" Air 130mm fork absorbs rough terrain with ease
  • Shimano 9-speed drivetrain and hydraulic disc brakes deliver durable performance
  • Single sided hardware offer easy maintenance access to main pivots
