Stumpjumper Comp Alloy 27.5
The Stumpjumper Comp Alloy 27.5 combines the balanced stiffness and incredible precision of our sidearm frame design with a 12-speed SRAM NX Eagle drivetrain. The end result is a bike that outperforms its price tag by a wide margin.
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.
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. Total control.
MASSIVE BANG FOR YOUR BUCK
• Sidearm frame design offers balanced stiffness and precise handling.
• FOX DPS Performance rear shock delivers perfectly-dialed rear suspension.
• NX Eagle 12-speed drivetrain gives you single-ring simplicity and gearing to spare.
