Specialized Stumpjumper 15 Expert

The GENIE technology is designed to provide the plush, ground-hugging traction of a coil spring while retaining the bottom-out resistance and adjustability of an air spring. It effectively eliminates the harshness often found in the middle of an air shock's stroke, giving you more grip on technical terrain without sacrificing support.

Yes, the Stumpjumper 15 is designed to be versatile. You can run it as a full 29-inch setup for maximum rollover capability or configure it as a mullet setup with a 27.5-inch rear wheel for increased maneuverability and clearance in tight, steep sections.

The bike features adjustable geometry that allows you to fine-tune the head tube angle and bottom bracket height. This lets you tailor the handling to your specific riding style and the terrain you frequent, whether you prefer a more stable, slack feel or a sharper, more responsive ride.

Yes, the internal storage system is integrated directly into the downtube and is designed to securely hold trail essentials like a tube, pump, or multi-tool. It keeps the weight low in the frame for better handling and keeps your pockets or pack free of heavy gear.

The wireless electronic drivetrain is highly reliable and requires less maintenance than traditional cable-actuated systems because there are no cables to stretch or housing to clog. You simply need to keep the battery charged and ensure the derailleur hanger is straight, as the system is designed to be robust and precise under load.

The Stumpjumper 15 is built for versatility, balancing big-hit capability with efficient pedaling performance. It is well-suited for long, demanding trail rides where you need a bike that climbs efficiently but remains composed and playful on technical descents.
