More Epic than Enduro, this new Stumpjumper is a thoroughbred speed machine.
Lively and responsive
Precise handling
Lightweight
Not as versatile as previous Stumpjumpers
Unforgiving of poor setup
Flex stays only available on carbon models

‘Total control, unparalleled bump-eating suspension, and a fine-tunable geometry are hallmarks of the all-new Stumpjumper EVO Expert. ‘ Lofty words from Specialized to say the least! Long time [R] tester Blake Nielsen got his hands dirty onboard their new Swiss Army knife of bikes on everything he could, from home trails to Thredbo. Read on! Reviewer // Blake Nielsen Photos // Matt Staggs Let’s start nice and easy with your first impression of the Evo once it arrived at [R]evo’s […]

The 2021 Specialized Stumpjumper Expert is a completely refreshed model with updated geometry and – on the carbon models – a new suspension platform with flex stays instead of a lower pivot. In this spec it's an incredible all rounder, though the price is undeniably steep. I guess you do get SWAT, though...

The 2021 Stumpjumper gets an all-new frame design, and that translates to a big difference out on the trail.
Impossibly well-rounded. Want to cover all the miles? Sure. Want to ride stupid stuff? Be smart and sure.
Riders who recognize and appreciate a fast, energetic-feeling bike are going to love the new Stumpy.
When push comes to shove on hectic trails, the Stumpy isn’t as much of a bike as the Salsa, P-Train, etc. It’s not meant to be, though

The moment that Specialized revamped its venerated Stumpjumper for 2021, I was chomping at the bit to see what the redesigned trail bike was all about. My first introduction was to the Stumpjumper EVO Expert, a rowdy all-rounder that I absolutely loved. So, when I got a chance to test its sibling, the Stumpjumper Expert, I was eager to find out how it stacked up against the EVO. I had a hard time concealing my curiosity when I noticed that the Stumpjumper Expert was missing Specialized’s signature FSR suspension design. To save weight, the bike’s designers opted for a lightweight flex stay rather than the traditional chainstay pivot point. I was so keen to try it out that I immediately took it on a few small hot laps on the “test track” outside my apartment, which is, no joke, a stump I love to jump. I immediately knew the Stumpjumper Expert was ready for some of Galbraith Mountain’s rowdiest trails. Most of my favorite rides involve an hour or more of climbing before a quick, high-speed descent. So, as one could expect, I have a soft spot for bikes that climb exceptionally well. The new Stumpjumper Expert made my time climbing a joy. The kinematics of the 130-millimeter rear shock helped to keep the momentum moving forward, regardless of whether I was pedaling in or out of the saddle. I never felt the need to reach down and flip into “climb” mode on the Fox Float DPS Performance Elite shock while climbing. The suspension showed an excellent mix of traction-generating squish, while also delivering some zippy acceleration—something that was accentuated by the Specialized Purgatory rear tire. The seat angle was just steep enough to keep the bike balanced on steep, punchy climbs, even while seated.

Specialized’s standard Stumpjumper hopes to please the masses with revised geometry and updated specs
Great fun to ride on bridleways and tamer trails
Good balance between price and performance
Dropper post travel inadequate
Be good to see option to spec a Fox 36, RockShox Pike or Lyrik because the Fox 34 lets the bike down once the trails get tougher

The latest Stumpjumper is less an overhaul and more an evolution but t's still been subject to many updates including a step away from the Horst Link suspension design we're used to seeing on the Stumpjumper model.
