THE ULTIMATE TRAIL BIKE

The innovative sidearm frame design makes a lighter, better-handling bike. By directly connecting all three mounting points of the rear-end and shock to the frame, we’ve increased both stiffness and performance over bumps. End result? Total control.

PERFECTLY-BALANCED SUSPENSION

Our in-house suspension-tuning team develops custom shock tunes, perfectly paired to each bike’s kinematics. We call this Rx Tune and while it’s not the easy way to build a suspension bike, it’s worth it. You feel Rx Tune as perfectly-balanced suspension.

SMART PARTS PICK

• 29er wheels roll over obstacles and maintain your momentum with ease.

• 130-millimeters of suspension courtesy of a RockShox Recon RL fork.

• SX Eagle 12-speed drivetrain gives you single-ring simplicity and gearing to spare.

 

  • The M5 alloy frame, asymmetrical “sidearm” design, and our 29er Geometry, make this Stumpjumper both capable and efficient.
  • 130-millimeters of plush and controlled suspension (including a lock-out) come courtesy of a RockShox Recon RL fork.
  • SX Eagle 12-speed drivetrain gives you single-ring simplicity and all the gearing you need to summit the biggest climbs.
  • 29er wheels roll over obstacles and maintain your momentum with ease.
  • The TranzX seatpost lets you drop your saddle on descents, increasing your maneuverability and control when the trail gets dicey.
