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.

[First Ride] 2021 Specialized Stumpjumper S-Works

Oct 2020 · Ian Collins

If you saw the news about the revised 2021 Specialized Stumpjumper EVO last week, you may have wondered if and when a new classic Stumpjumper was coming. Well, wonder no more because it’s here. Last month I was fortunate enough to spend some time in Oakridge, Oregon and the Gifford Pinchot Forest in Washington riding the new rig on the same trails that the legendary Trans Cascadia takes place on. I tested the flagship S-Works model, which has 140mm of front travel mated to 130mm out back. So, gone is the separation of a 140mm Stumpy and a 120mm Stumpy

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.

Specialized Stumpjumper Evo Expert review

Oct 2020 · Guy Kesteven

Specialized’s Stumpjumper Evo Expert is a lightweight carbon daily driver with downhill geometry, but does that work on the trail?

Highs
  • Rad-to-mad geo and shock adjustment

  • Excellent suspension control

  • On-point frame feel

  • Decent weight

  • SWAT

  • Practical, protective details

  • Sorted kit package

  • Full size range

Lows
  • Power phase is soft in open mode

  • S-Works frame is a lot more cash for just a 35g weight saving

  • Tires are dry biased

  • Shorter stem please
