Features specialized bike sj 15 sw ltd 2025
The S-Works Stumpjumper 15 LTD is designed so that you don't have to make any compromises while riding on the trails. Does it devour potholes like a downhill bike? Of course. Is it short travel and is the pedaling super efficient? Yes of course. Can you switch between these two scenarios without touching a button? We present the new S-Works Stumpjumper LTD with FOX Live Valve Neo suspension.
Kinematics refinement: As the quintessential trail bike, it should come as no surprise that the Stumpjumper 15 perfectly balances efficiency and shock absorption. As for the anti-squat, we have sought a balance between the Stumpjumper and the Stumpjumper EVO, both with excellent pedaling.
The SWAT 4.0 of the Stumpjumper 15 offers more storage space in the down tube, an innovation we pioneered. It is the easiest and most weather-resistant storage system of its kind in the world.
Live Valve Neo is an ultra-fast, wireless rear suspension system that automatically switches between its two modes (active and firm) with impressive speed. FOX Neo is the fastest wireless communication technology in the cycling world: 100 times faster than Bluetooth. In addition to being very simple to use, the system can be adjusted in a thousand different ways using the FOX Bike app. It gives you more typical XC pedaling efficiency and the downhill capability of long-travel bikes.
