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 Stumpjumper ST Expert 29 gets right to the point. It has big wheels, 140mm of travel, a carbon frame with SWAT Door integration, and RockShox air suspension front and rear. SRAM Guide R brakes and a SRAM Eagle GX 12-speed drivetrain go nicely with the Roval Traverse carbon rims and a Command IRcc dropper post. This bike is light, fast, and beyond capable to ensure that nothing will ever hold you back on the trail.
