Specialized Stumpjumper 15 EVO Alloy Comp Description:

The Specialized Stumpjumper 15 EVO Alloy Comp mountain bike is an all in one quiver killer of a mountain bike to rule the trails. At the heart of this versatile rig is an aggressively shaped M5 aluminum super alloy main frame and rear swing arm, and the engineers have given this robust, yet lightweight, construction a geometry that puts the rider in a balanced position where they can easily maneuver around the bike. Furthermore, there are various geometry adjustment points that allow the rider to fine tune the performance of the bike to suit their unique needs. Out back, the rear suspension kinematics are the latest evolution of Specialized’s “four-bar” Horst-link FSR suspension design that isolates braking and pedaling forces from the suspension movement, providing a plush ride quality with exceptional traction throughout the travel range.

This remarkable frame deserves a spec to accentuate its versatility, and this bike does not disappoint. A Fox 36 Rhythm fork fitted with a GRIP damper and a Fox Float X Performance rear shock with custom Specialized GENIE internals/valving keep the bike firmly planted and stable over rowdy terrain. SRAM’s Eagle 70 transmission mechanical drivetrain delivers a broad gear range, is easy and inexpensive to maintain, and provides precise shifting. When it is time to check the speed or come to a stop, a combination of large disc rotors and powerful 4-piston SRAM DB8 hydraulic disc brakes deliver confident braking in any weather or trail conditions. Sturdy Specialized hookless and tubeless ready alloy wheels are wrapped in very grippy Butcher and Eliminator tires that will deliver confident performance over a variety of trail conditions. Completing the parts list are an Xfusion Manic dropper post topped with a Specialized Bridge Comp saddle, a Specialized alloy handlebar and Trail stem, and lock-on style grips, ensuring the touch points get the same level of love and performance as the rest of this incredible bike. When you are looking for one bike for a fun time on the trails, the Specialized Stumpjumper 15 EVO Alloy Comp mountain bike delivers the goods!
