The Specialized Stumpjumper 15 EVO Comp is a versatile carbon trail bike designed for riders who want confident descending performance without giving up responsive handling or climbing efficiency. Its FACT 11m carbon frame, 160mm FOX 36 fork and GENIE-equipped FOX FLOAT X shock provide the control needed for demanding terrain, while adjustable geometry allows the bike to be tailored to different trails and riding styles.
Lightweight FACT 11m Carbon Frame
The FACT 11m carbon chassis reduces weight while maintaining the strength and stiffness needed for technical trail riding. At a claimed 15.45kg in size S4, the Stumpjumper 15 EVO Comp feels easier to accelerate, manoeuvre and pedal over longer distances than its aluminium counterpart.
The carbon rear end, threaded bottom bracket, sealed pivot bearings and SRAM UDH compatibility also create a practical platform designed for regular riding and straightforward servicing.
FOX 36 Rhythm Control
The FOX FLOAT 36 Rhythm fork provides 160mm of travel on sizes S2 to S6, giving the bike accurate steering and dependable support through steep or rough sections. Its GRIP damper is easy to adjust and provides predictable control without requiring a complicated setup.
Size S1 receives 150mm of travel to maintain balanced handling and suitable proportions for smaller riders.
GENIE Suspension Performance
The FOX FLOAT X Performance shock uses Specialized GENIE air-spring technology to combine sensitivity over smaller bumps with progressive support deeper in the travel. This helps the rear wheel maintain traction across roots, rocks and braking bumps while reducing harsh bottom-outs on bigger impacts.
The external reservoir manages heat during longer descents, while the two-position lever and three-setting Open mode tuning range allow riders to adjust the shock for their terrain and preferences.
Adjustable Trail Geometry
The Stumpjumper 15 EVO provides six geometry configurations through its adjustable head angle and bottom bracket height. Riders can choose a lower, slacker position for greater stability on steep trails or a higher setting for increased pedal clearance and more responsive handling.
This adjustability makes it possible to fine-tune the bike without replacing major components.
SRAM S1000 Eagle AXS Transmission
The SRAM S1000 Eagle AXS rear derailleur provides wireless electronic shifting through an AXS Pod controller. Shifts remain precise under load, while the wide-range 10–52-tooth cassette provides suitable gearing for steep climbs and faster trail sections.
The direct-mount T-Type design creates a robust drivetrain with no conventional derailleur hanger. The removable battery also makes charging and carrying a spare straightforward.
Powerful SRAM Maven Braking
SRAM Maven four-piston hydraulic brakes provide the power needed to control speed on steep and sustained descents. Their strong braking performance means less effort is required at the lever, helping reduce hand fatigue and allowing riders to focus on line choice.

Our Thoughts on the Specialized Stumpjumper 15 EVO Comp
The Specialized Stumpjumper 15 EVO Comp represents one of the strongest all-round options in the Stumpjumper range. The FACT 11m carbon frame offers a meaningful weight saving over the Comp Alloy, while the FOX 36 Rhythm fork and GENIE-equipped FLOAT X shock provide the control needed for technical trail riding.
