Specialized Stumpjumper EVO Comp Custom - 2024, S4/Large

The 2024 Specialized Stumpjumper EVO Comp AXS Custom is the definitive benchmark for aggressive all-mountain performance, engineered to blend blistering trail efficiency with the bottomless descending authority of a full-blown enduro rig. Sculpted around Specialized's highly modular S4 geometry—the modern, long-reach equivalent to a traditional Large—this aggressive trail weapon delivers an incredibly planted and confident footprint optimized to fit pilots between 5'8" and 6'2". The asymmetrical chassis is meticulously formed from the brand's premium FACT 11m carbon fiber construction, which positions a structural reinforcement strut alongside the shock to optimize frame stiffness, while cleanly nesting a spacious SWAT™ Door internal frame storage hatch within the down tube to hide ride essentials completely out of the wind. Originally retailing at an exceptional value of $3,550, this custom build represents a dominant balance of premium carbon engineering and elite electronic integration.

The wireless electronic infrastructure features a custom off-road-proven configuration built around a 1x12-speed SRAM GX Eagle AXS electronic ecosystem. Distinct from the newer direct-mount transmissions, this setup utilizes the highly responsive, standard-hanger previous generation AXS ecosystem to deliver instantaneous, crisp gear changes at the single click of an AXS controller. Power is driven efficiently through structural 170mm SRAM GX crank arms spinning a durable 32T direct-mount X-Sync 2 chainring. For maximum drivetrain longevity and a massive mechanical advantage on steep walls, the system is custom-built with premium, quick-engaging Shimano hubs laced to a wide-range 11-51T Shimano Deore XT cassette. When diving hot into technical singletrack, stopping power is absolute and precise, governed by heavy-duty SRAM Code RS 4-piston hydraulic disc brakes clamp-matched to oversized 200mm Centerline rotors for fade-free control down prolonged mountain slopes.

The suspension kinematics are tuned to deliver a zero-compromise, ground-hugging ride quality across 150mm of active rear wheel travel. The rear end traction is governed by a piggyback Fox Float X Performance rear shock carrying an EVOL air sleeve and a 2-position compression adjustment lever to firm up the chassis on grueling fire road climbs. Up front, front-end compliance is managed by a stout-chassis Marzocchi Bomber Z1 fork carrying 160mm of travel, running a proven Fox GRIP damper to track flawlessly through loose berms and blown-out rock gardens. The rolling stock features durable, premium enduro double-wall alloy hookless rims spinning on smooth Shimano hubs, wrapped in a high-end Maxxis rubber combination featuring an aggressive 29x2.50" Maxxis Minion DHF tire up front for pinpoint steering traction and a fast-rolling 29x2.40" Maxxis Dissector tire in the rear to maximize cornering bite. The high-end build is beautifully completed with an alloy trail handlebar cockpit, an exceptionally smooth X-Fusion Manic dropper seatpost, and a supportive Specialized Bridge Comp saddle carrying hollow Cr-Mo rails. This turn-key Stumpjumper EVO arrives fully configured tubeless and completely ready to conquer your local backcountry trail loops.
