2021 SPECIALIZED S-WORKS STUMPJUMPER MOUNTAIN BIKE
The Specialized S-Works Stumpjumper Mountain Bike is going to change your perceptions of what a trail bike is capable of. With a boutique spec list stacked with top-tier components and an all-new frame design, it is a zero-compromise option for the most elite of cyclists. Although visually similar, this latest generation of Stumpjumper is a new beast altogether. Retaining the side-arm design, Specialized have built an incredibly versatile bike perfect for a wide range of riders.

Designed for outright speed, this latest frame features a roomy top tube and confidence-inspiring angles for a planted feel, no matter how rowdy the line. Revised suspension kinematics create a ride like no other, offering lively characteristics perfect for popping lips and pumping free-speed out of the trail. A progressive leverage curve gives the Stumpjumper a bottomless feel, using every bit of the 130mm on offer to propel you down the descents. Excellent small bump management and a specific RX Trail Tune ensure glue-like grip on loose terrain, balanced with big-hit performance for when things go awry.

Rider-First Engineered™ sizing ensures a perfect, style-specific fit. With low seat-tube heights, riders of all statures can reap the benefits of a more stable or playful ride depending on their preference. Size up for a more planted ride, size down for manoeuvrability - the choice is yours. A yoke mounted flip-chip allows for further fine-tuning, allowing you to drop the BB and slacken out the head angle by half a degree for a more aggressive ride. 29-inch wheels are the size of choice for the planets fastest riders, which sees the Stumpjumper move solely to a big-wheel specific platform for this latest generation.

It would not be an S-Works without a top of the range parts list, and it sure does deliver. The state of the art wireless SRAM XX1 Eagle AXS drivetrain provides near-telepathic performance, with easy setup and incredibly lightweight components. SRAM’s top-spec G2 ULTIMATE four-piston brakes provide incredible stopping power and a solid, direct feel. The cockpit sees carbon Specialized bars clamped by Deity’s performance-focused Copperhead stem and tacky Knuckleduster grips, bringing aftermarket performance to an off-the-shelf bike. Roval Control 240 rims are married to DT Swiss 240 Ratchet EXP hubs for near-instant engagement and rapid acceleration, and the suspension is managed by the flagship FOX Factory 34 and DPS respectively.
