Specialized Stumpjumper Review
This Stumpjumper model is ready to handle everything from fast descents to technical climbs. Its M5 alloy frame not only provides durability but also includes Specialized's innovative SWAT™ Door integration for extra storage. The Fox suspension is dialled in for aggressive trail riding, with 160mm travel up front and 145mm at the rear to handle the roughest tracks. Plus, the Shimano SLX drivetrain ensures reliable shifting, giving you the confidence to ride harder without worrying about performance drops.
The TRP DH-R EVO 4-piston brakes deliver serious stopping power, helping you control your descents with ease. Roval Traverse wheels, combined with Butcher GRID TRAIL tyres, provide excellent grip and stability, whether you're flying down the trail or navigating tricky sections.
With personalisation options like adjustable suspension and geometry, the Stumpjumper 15 is a bike that adapts to your unique riding style. And with 0% APR finance available, it’s easier to get this trail beast onto the track.

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.
