Specialized Stumpjumper 15 Review

The Stumpjumper 15 is designed to obliterate every trade-off in the trail game. With its lightweight FACT 11m carbon frame, it is both durable and agile, perfect for aggressive trail riding. The Öhlins suspension system, including the RXF38 M.2 fork and TTX 22 M Coil rear shock, provides superior control and responsiveness, allowing you to devour bumps and maintain stability on rough terrain.

The bike's geometry delivers big bike capability with a nimble feel in tight sections and efficient climbing manners. The S-Sizing system allows you to choose the size that best suits your riding style, ensuring optimal handling and comfort. Whether you're descending technical terrain or climbing steep trails, the Stumpjumper 15 offers the capability and control you need to enjoy every ride.

Specialized's innovative GENIE Shock Technology grants every trail rider's three wishes: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable platform for a playful feel. This suspension system allows the bike to handle big terrain calmly while maintaining a poppy feel for shorter travel.

This bike is a testament to Specialized's commitment to enhancing the trail riding experience, focusing on making the best moments better and eliminating the bummers. With its advanced suspension technology and thoughtful design, the Stumpjumper 15 sets a new standard in trail bike performance.

Occasionally, without notice, manufacturers change product design and/or specifications.

Find your S Size

Determining your S-Size is easy. If you rode a Medium before, then S-3 will be your equivalent size. But if you want a more nimble ride, you should drop down to an S2. Want a bike that’s more stable at speed? Bump up to an S4. Following are examples of three riders, all 5’8” (1.73m), who chose three different sizes.
