Specialized Stumpjumper EVO Comp Alloy

£3,250.00

Let’s get something clear the Stumpjumper EVO Alloy isn’t a “normal” trail bike. It’s built to get gnarly plain and simple.

Top it off with a build that blends quality, affordability, and durability, and it’s the perfect trail partner, no matter where those trails are, or how rowdy they get.

All the travel in the world is useless without the proper kinematics. Applying lessons learned while developing the Enduro and following that with more than 1000 hours of development, Specialized improved the pedaling performance, making it more capable, agile, and lively. Bottom line? This thing shreds trails, not legs.

PROGRESSIVE GEOMETRY — The S-Sizing geometry of the new Stumpjumper hits the sweet spot. It’s long, low and slack, with a short offset fork and a steeper seat tube angle. FlipChip adjustability allows fine-tuning, ensuring that your new Stumpjumper performs flawlessly.

RIDER-FIRST ENGINEERED™ — RFE frames use a size-specific approach to ride characteristics that ensures benchmark handling and flawless performance. Whether riding an S1 or an S6, you’ll experience the same ride traits – rail-sharp cornering and balanced front and rear stiffness – at the lightest-possible weight.

SWAT™ — When Specialized introduced the SWAT™ door on the Stumpjumper in 2016, they increased space, and added room for those “oh s**t” pumps and flat accessories. The new Stumpjumper has the same hallmarks that you know and love.
