Specialized Stumpjumper Fsr St Men Comp 29 Features

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.
A NO-NONSENSE BUILD
• Sidearm frame design offers balanced stiffness and precise handling.
• The FOX DPS Performance rear shock equals perfectly dialed rear-suspension.
• FOX FLOAT Rhythm 34 fork with 130mm of travel offers great adjustabiity.
