The Stumpjumper EVO got a complete overhaul for 2021, taking it from a dedicated long and slack brawler to a genre-bending chameleon of a bike. 150mm FSR...

The Specialized Stumpjumper Evo Comp Alloy has one of the smartest metal frames we’ve seen, but is that quality reflected in the specs?
Excellent easily tuneable geometry
Great aggro tire choice
Short seat tube for size switching
Solid climb mode
Stiff power transfer
SWAT and geometry switching add cost
Slow free hub pick up
Chunky weight

At The Loam Wolf, we’d rather have a bike that rides well than a bad bike made from carbon fiber. Read a full review on the Specialized Stumpjumper Evo Alloy!
Aluminum
SWAT Door
Comfortable and confident
Playful and fun to ride
Fast
Big geo adjustments
Value is debatable

Bridging the gap between tours, climbs and descents?
Intuitive, good-natured handling
SWAT features and great build quality
Bridges the gap between touring, uphill and singletrail performance
Puncture-prone tires paired with XC carbon wheelset
Brakes overheat quickly and require strong fingers on long rides

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 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.
