We deliver! Just say when and how.
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.
The Stumpjumper EVO Elite Alloy is built to brawl, no question. With a bullet-proof SRAM GX Eagle 12-speed drivetrain, stout 30mm-wide alloy wheels, and Rx Tuned RockShox suspension, there’s no trail too rowdy.
