Specialized Stumpjumper EVO Comp Alloy Mountain Bike 2023

Stumpjumper EVO Comp Alloy

Let's get something clear, the Stumpjumper EVO Alloy isn't a "normal" trail bike. It's built to get gnarly, plain and simple. Featuring the same all-new design as its carbon brethren—including an adjustable head tube angle, 150mm of performance tuned travel, the adaptability of S-Sizing, and SWAT™ Door integration—in a lightweight yet tough M5 Alloy chassis, you're going to be able to bomb down trails that you thought you couldn't touch without a full-blown DH rig.

Spec’d with a no-fuss SRAM NX Eagle 12-speed drivetrain, bomber 30mm-wide alloy wheels, and plush Fox FLOAT Performance suspension, there’s no question the Stumpjumper EVO Comp Alloy is dressed to shred.
