Bike Review | 2021 Specialized Stumpjumper EVO Expert

Oct 2020 · Spencer Johnson

The storied Specialized Stumpjumper EVO—arguably the most famous mountain bike model in the history of our sport—is back for 2021, and the newest incarnation feels more refined and adjustable than ever before. With a headtube angle that’s adjustable from 65.5 degrees all the way down to 63 degrees, and a bottom bracket with height adjustability from 32 millimeters of drop to a ground-hugging 39 millimeters of drop, the new Stumpjumper EVO Expert we tested comes with multiple geometry options that can radically change its personality on a wide variety of terrain. The 2021 Stumpjumper EVO certainly has retained some of the climbing characteristics of its previous iteration. Specifically, it’s a bike that is far better to climb in the seated position than hammering out of the saddle—a trait attributed to the FSR suspension platform, which gives impressive traction through chunky terrain while climbing in the seated position. While climbing in the seated position, my weight felt balanced between the front and rear wheels, allowing me to stay comfortable and in control on even the steepest of climbs. I found the lowest bottom-bracket setting to be the best for climbing, as it extends the chainstay dimensions, adding to its overall stability. When it came to dialing in the compression on the super-active Fox Float DPX2 Performance Elite shock, I preferred switching it into the middle setting on the climb switch to slightly stiffen the pedaling platform.

Specialized Stumpjumper ST COMP 2020 on test – Comfort as a major strength?

Aug 2020 · Christoph Bayer

The Specialized Stumpjumper ST COMP is the big loser in our trail bike group test. Despite looking great, it ultimately couldn't deliver. What went wrong?

Highs
  • Very comfortable contact points

  • Aesthetically pleasing

  • Intuitive and good-natured handling

Lows
  • Suspension bottoms out easily

  • Lots of pedal bob

  • Poor spec for the price

Specialized S-Works Stumpjumper ST 29 review

Sep 2019 · Mick Kirkman

While hard to recommend as a complete package, this Stumpy still rips smoother trails to pieces

Highs
  • Corners like an absolute demon and feels super-reactive

  • Flickable and fun any time there’s even a hint of getting airborne

Lows
  • Beats you up at both ends over rough, repeated stutter-bumps and holes

  • Specialized’s latest GRIPTON tyres feel sketchy and vague

Specialized Stumpjumper ST Comp Carbon Review

Sep 2019 · Jim Bland

The Specialized Stumpjumper ST is understated and always left us yearning for more

Highs
  • Lightweight full carbon S-Works level frame with SWAT box, flip chip and massive tyre clearance

  • Agile, short and steep handing means awesome close combat agility and corner slashing fun

Lows
  • Lacks the zip and urgency shorter travel bikes provide due to a hefty overall weight

  • Limited suspension forgiveness when the going gets rough
