Specialized S-Works Stumpjumper MTB Frameset 2021

Specialized S-Works Stumpjumper MTB Frameset

Designed to meet the needs of the modern elite trail rider, the all-new Specialized S-Works Stumpjumper MTB Frameset is lighter, faster and designed to rip trails like never before. With full 11m carbon construction, the Stumpjumper is ultralight and features revised suspension kinematics for improved pedalling efficiency and fun, lively ride character. Although aesthetically similar to the previous generation, this all-new model has been meticulously redesigned to be Specialized’s fastest trail bike to date.

Rider-First Engineered™ design offers style-specific sizing, allowing you to choose a size to suit your style and not your height. For a more stable ride, size up to reap the benefits of a long wheelbase. For a more playful ride, size down for shorter reach measurements and increased manoeuvrability - the choice is yours. Much like the worlds fastest riders, all models in the Stumpjumper range now exclusively use 29" wheels, improving rolling speed on rough terrain and providing higher overall top speeds.

Revamped geometry figures see roomier cockpits throughout the size range, with slack head angles and low bottom bracket heights offering an uber-planted ride character on rough terrain. Revised kinematics sees a progressive leverage curve, designed to offer excellent small-bump compliance on chattery terrain and big-hit performance for heavier landings. No longer a Horst link layout, the use of flexstays drops the frame weight to a scant 2,250 grams and improves stiffness in the rear triangle. Short on travel but not short on fun, the S-Works Stumpjumper frameset uses 130mm of highly optimised suspension to climb and descend like no other trail bike before it.

With a stacked list of frame features, the latest generation of Stumpjumper is as high-tech as they come. SWAT™ Door integration makes a welcome return, now featuring increased storage space for your accessories, spares and nutrition. One for the mechanics, fully enclosed internal routing is a dream to set up. No cable fishing necessary, just push your housing or hose through for zero-fuss maintenance. A threaded bottom bracket is standard on the Stumpjumper, providing creak-free performance and easy home replacement. Extended chain slap protection ensures a silent ride, with a ribbed design all but eliminating drivetrain noise. 

The FOX FLOAT DPS Factory rear shock features the Specialized RX Trail Tune, specifically designed for improved performance on the trail. Kashima coating keeps breakaway force to a minimum, and the EVOL Air Sleeve increases air chamber volume for improved small bump sensitivity.
