The Stumpjumper has been making smiles for almost 40 years, and the latest iteration is no exception. Specialized threw every bit of knowledge they’ve acquired over the last 4 decades at the latest Stumpjumper and ended up creating one of the best trail bikes ever made. They gave it great climbing manners, a progressive leverage ratio, and multiple layouts to suit every riding style. The sidearm frame design is not only stiffer but also lighter and stronger, all while adding some asymmetrical flare to the bike’s already clean lines.
The S-Works Stumpjumper 27.5 is a subtle superbike that might get overlooked to a less-than-discerning eye. It followed a strict diet of carbon fiber and radness to deliver an ultra-lightweight trail bike that can breeze up climbs and shred descents with its FOX Factory suspension and Roval carbon wheels. SRAM Guide RSC brakes and XX1 Eagle drivetrain pair together for fantastic modulation and unimaginable crisp shifting. Specialized wanted you to have your cake and be able to eat it too.
