Specialized Stumpjumper Comp Alloy 27.5
No need to fret—we haven’t forgotten about all you alloy fans out there. In fact, the new Stumpjumper Comp Alloy 27.5 may be the most radically designed alloy bike ever made. For real, though. And with new tube shapes, an asymmetrical design, and the nimble 27.5 handling that we all love, it's plenty capable and ready to take on the trail.
- The completely redesigned alloy Stumpjumper frame features an M5 alloy front- and rear-end, an asymmetrical design, and our 27.5 Trail Geometry, so it's just the right amount of both capable and comfortable.
- The FOX DPS Performance rear shock features our Rx Trail Tune, ensuring that no matter the wheel or frame size, your bike is dialed-in perfectly.
- A FOX 34 Rhythm fork handles suspension duties up front, with stiff stanchions and plenty of adjustability.
