2021 Specialized Stumpjumper Expert review

Dec 2020

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...

Bike Review | 2021 Specialized Stumpjumper Expert

Nov 2020 · Spencer Johnson

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.
