The Stumpjumper ST is the short-travel version of the super versatile classic. It promises to be even more efficient while still being a lot of fun to ride. Can it still perform as well in every situation with less travel?

The Specialized Stumpjumper is synonymous with versatility. It has long been shaping the progression of our sport and has already gone through several evolutionary stages. The Stumpjumper ST is the short-travel version of the popular classic. With 120 mm travel at the rear and 130 mm up front, it has 20 mm less than the standard version and is said to offer even more efficiency, making it more suitable for all-day or multi-day rides. Priced at € 3,099, it is the second most expensive bike in the test. However, inauspiciously it is the heaviest model and also the least well-specced.

Specialized are the only manufacturer to spec Shimano’s lower range SLX 1×11 drivetrain. The FOX suspension, a 34 Rhythm fork and a FLOAT DPS Performance shock are standard in this price range. The Shimano MT501 brakes are nothing special but they offer decent braking power thanks to the large rotors. On the other hand, Specialized deserve praise for the various contact points. The handlebar, stem, grips and saddle are perfect, offering lots of comfort and great ergonomics. Specialized’s in-house Eliminator and Purgatory tire combination also performed convincingly on the trail.

The Specialized tires offer a lot of grip with low rolling resistance and good puncture protection.
High quality
The frame of the Stumpjumper ST looks high-quality with beautiful details such as the thickly padded chainstay protector.
Blast from the past
By now, 1×12 drivetrains are ubiquitous across all price points. The 1×11 model specced here is no longer in keeping with the times. The low gear range limits the bike’s suitability for longer rides.

Specific Features

Very comfortable
Saddles and grips are subject to personal preference, but Specialized’s in-house products were well received by all of our test riders. Once you climb aboard, you won’t want to get off.
The climb switch on the shock is a very necessary feature both on the climbs and descents. It suppresses pedal bob on the climbs and provides more support on flowing trails when you descend.

The geometry of the Specialized Stumpjumper ST

Specialized was one of the first brands to start designing their bikes with shorter seat tubes. This has the advantage that you can choose the bike’s size not by its height but by its length. You’re also able to fit longer dropper posts. The reach of our size L test bike is compact at 455 mm, but the bottom bracket is very low with a drop of 39 mm. The respective head and seat tube angles of 67.5° and 75.1° in the slack setting are rather conservative. The Stumpy also features a flip chip. We only rode the bike in the slacker of the two settings.

Before you swing your leg over the Specialized Stumpjumper ST, it makes sense to push the saddle as far forward as possible. That way the riding position is sufficiently central and comfortable and you’ll feel at home from the get-go. Riding uphill, it is worth activating the climb switch regardless of terrain given that the suspension bobs noticeably and tends to wallow on steep climbs. On technical climbs, the Stumpy delivers lots of traction, but you have to pay attention to the position of your pedals due to the low bottom bracket. You’ll be happy about the 30 t chainring on steep climbs because, with a maximum of 46 teeth on the cassette, the gear range is limited.

The geometry is great, unfortunately, the suspension isn’t! Downhill, the Stumpy quickly reaches its limits.

Going downhill, you’ll also notice how low the bottom bracket is but only in a positive sense. As the rider, you feel securely integrated with the Specialized Stumpjumper ST, instilling you with confidence and also making the bike feel super balanced through the corners. The Stumpy’s handling is intuitive and good-natured. It’s agile and direct in tight sections and requires little rider input. Beginners and passive riders will be happiest with this bike. The major weakness of the Stumpjumper ST is its rear suspension. Despite the large 0.6 cm3 volume spacer fitted as standard, the suspension is far too linear and bottoms out harshly even at moderate speeds and with medium impacts. Should you decide to send it, your ankles and the rear rim will be cursing you later.

How does the Stumpjumper compare to the competition?

Despite only 120 mm travel at the rear, the Stumpjumper needs a lot of encouragement on the climbs and quickly falls behind the competition. Besides the inefficient rear suspension, the back-heavy riding position doesn’t help either. However, the handling on the descents is good-natured, similar to that of the Neuron with the comfort of the SCOTT Genius. Unfortunately, it’s too generous with its travel and quickly bottoms out. That makes the bike unsuitable for rough trails.

Tuning tips: We would recommend going for the longer travel Stumpjumper COMP Alu 29, which even has a 1×12 drivetrain for the same price

Intended Use










The Specialized Stumpjumper ST COMP is only suitable for relaxed riders who value comfort and prefer moderate terrain and going slow on the descents. Its handling is good-natured and intuitive, but its suspension isn’t up to the task. Unfortunately, the componentry leaves a lot to be desired considering the price. We recommend choosing the longer travel Stumpjumper COMP 29!


  • very comfortable contact points
  • aesthetically pleasing
  • intuitive and good-natured handling


  • suspension bottoms out easily
  • lots of pedal bob
  • poor spec for the price
