A Premium Carbon Platform for a Custom Trail-Bike Build.
The S-Works Stumpjumper 15 EVO Frameset gives you the foundation for a light, capable and highly adjustable trail bike. Its FACT 11m carbon frame combines confident descending performance with the lively handling and pedalling efficiency that make a trail bike enjoyable across a full day of riding.
A RockShox Super Deluxe Ultimate rear shock with Specialized GENIE suspension technology is included. Adjustable trail geometry, internal SWAT storage and plenty of setup options allow the finished bike to be tuned around your terrain, riding style and component preferences.
FACT 11m Carbon Construction
The FACT 11m carbon frame and carbon shock link keep weight under control without turning the Stumpjumper into a nervous or overly delicate bike. It is designed to feel composed through rough sections while retaining the responsive handling needed for tighter trails and rolling terrain.
At a claimed 2.9kg, the frameset provides a strong starting point for a premium custom build. Final bike weight will depend on frame size, suspension setup and the components chosen.
RockShox Super Deluxe Ultimate with GENIE
The included RockShox Super Deluxe Ultimate shock uses Specialized GENIE technology to give the bike a supple feel over smaller bumps, useful mid-stroke support and stronger resistance to harsh bottom-outs.
This helps the Stumpjumper 15 EVO carry speed through rough sections without giving up the support needed when pumping through corners, compressions or rolling terrain. Shock pressure, damping and progression can still be adjusted to suit rider weight and riding style.
Adjustable Trail Geometry
Adjustable geometry allows the Stumpjumper 15 EVO to be set up around the trails you ride most often. A more neutral setting suits mixed trail riding, while a slacker setup adds confidence on steeper and faster terrain.
This flexibility also makes the frame a good platform for riders who like experimenting with cockpit, wheel and suspension choices rather than being locked into one factory configuration.
SWAT Internal Storage
Specialized SWAT Door integration provides storage inside the down tube for essential tools and riding supplies. It keeps commonly needed items on the bike, reducing the amount you need to carry in a pack or riding jersey.
Made for a Custom Build
This frameset is aimed at riders who already know what they want from their suspension, wheels and drivetrain. Starting with the frame lets you choose every component around your budget and riding priorities rather than replacing parts from a complete bike.

Our Thoughts on the S-Works Stumpjumper 15 EVO Frameset
The Stumpjumper 15 EVO is designed for riders who want one trail bike that can cover a broad range of terrain. It has enough suspension control for rough and demanding trails without losing the responsive feel that makes a shorter-travel bike enjoyable on everyday rides.
The GENIE-equipped Super Deluxe Ultimate shock is a worthwhile inclusion, while the adjustable geometry gives an experienced rider plenty of scope to refine the handling. We would recommend this frameset to someone building a premium trail bike around a carefully selected set of components rather than simply chasing the lightest possible build.
