The Stumpjumper EVO Alloy 27.5 is designed to conquer the gnarliest trails out there. We paired 150mm of smooth Stumpjumper suspension with seriously slack long & low geometry. It’s the perfect frame for anyone looking to build an absolute brawler. ONE FRAME ANY TRAIL The innovative sidearm frame design makes a lighter better-handling bike. By directly connecting all three mounting points of the rear-end & shock to the frame we’ve increased both stiffness & performance over bumps.

With their slacked-out front-end & longer top tube EVO models have heavier steering & exceptional front-end traction that beg you to do cutties & boost every lip. Get rowdy.
