S-Works Stumpjumper EVO
2021 S-Works Stumpjumper EVO
The S-Works Stumpjumper EVO is much more than just a trail bike, it’s a shred-sled built to full-send down the gnarliest trails. Featuring an all-new design, with an adjustable head tube angle, 150mm of performance tuned travel, and the adaptability of S-Sizing, this thing is an absolute ripper. The S-Works Stumpjumper EVO—get rowdy.
In true S-Works fashion, the S-Works Stumpjumper EVO is built to the hilt. A Fox Factory fork and rear shock handle suspension duties, while SRAM Code RSC four-piston brakes scrub speed, and a full SRAM AXS wireless groupset completes this lust-worthy build.
