Specialized S-Works Stumpjumper Evo Mountain Bike 2022
Sitting atop its product line, the Specialized S-Works Stumpjumper Evo Mountain Bike is the culmination of thousands of hours of product research and testing. Constructed from a high grade 11m carbon fibre, the frame is light, stiff and durable, and provides a ride character like no other on the trail. Synonymous with peak performance, the S-Works moniker signifies a premium specification, which in this case sees FOX factory suspension on the front and rear, a Roval carbon wheelset, and a fully wireless SRAM XX1 AXS groupset.
Now with increased storage capacity, the SWAT™ door allows you to carry a pump, tools and other accessories on the trail, without the need for a backpack. A 22oz SWAT™ is included to improve your water carrying capacity, which lends itself well to all-day riding. The geometry pushes the boundaries of trail-bike performance and offers an extreme degree of adjustability to allow for a custom-tuned ride-feel.
The boutique parts selection leaves nothing to be desired, with its top-shelf componentry being nothing short of dream-bike material. For exceptional acceleration and ultimate durability, the Roval Traverse SL 29 wheelset is ultralight and bombproof and utilises the DT Swiss Star Ratchet system for instantaneous engagement. The fully wireless SRAM XX1 AXS drivetrain is customisable through the accompanying app, and top-spec Code RSC brakes deliver confidence-inspiring stopping power for alpine-style descending.
