2020 Update

There are just a few tweaks to the Stumpjumper range for 2020. All the bikes now have a SRAM Eagle 1x12 speed drivetrain except the S-Works which has the new Shimano XTR 12 speed. The frame and the rest of the components remain the same apart form the Expert Carbon bikes which now have Fox suspension instead of RockShox.

Updated: 9th December 2019


The iconic Specialized Stumpjumper has been completely redesigned for 2019. With a distinctively different frame design, this is a bike that performs as good as it looks. It’s more capable than ever on challenging trails, yet still lightweight and playful. The new Stumpy we review here is sure to be one of the most-wanted-bikes of the season.

Specialized have increased the range with the introduction of new models. The short travel, Stumpjumper ST supersedes the Camber, while the Stumpjumper EVO offers more of a gravity focused ride. The Regular Stumpjumper featured here, is available with either 650b (27.5”) or 29” wheels. It has the same trail riding focus as the previous bikes but offers significantly better ride characteristics. Specialized have also made the new Stumpy much easier to live with, thanks to neat little tweaks that well go into later.

Specialized Stumpjumper Frame


Full carbon or alloy versions

The new Stumpjumper takes on a new look compared to previous models. The sidearm design directly connects the front and rear shock mounts. Specialized developed this single-sided design to improve stiffness, especially when the shock is in full compression. Longer than last years bikes, the reach has been increased by 13 – 27mm depending on frame size. This is combined with a slacker head angle – 65.5 degrees on the 27.5” wheel bike, 66.5 on the 29er – to give the Stumpy a thoroughly modern trail bike feel.

All the carbon bikes get a full carbon frame for 2019. This is made from the very highest-quality FACT 11m carbon fibre. This was previously reserved for the S-Works bikes. The SWAT door allows you to store your ride essentials in the downtube, and now features a simple design with a larger opening. The alloy bikes don’t get this extra storage capacity, but the ride characteristics are very much the same. The women’s bikes get female specific frame geometry, shock tunes and touch points.

It comfortably tackled long and draggy and steep and techy climbs, fast and loose and tight and technical descents, confirming it has all the capabilities required to be a good all-round trail bike that can handle a wide range of trail types. pinkbike

Specialized Stumpjumper rear shock


Improved suspension kinematics

The Stumpy is not only back in the game, it’s at the top of its game, because this is as good a Stumpjumper as I’ve ever ridden.

The suspension travel numbers are much the same as last years bikes – 150mm front and rear on the 27.5” wheeled bikes, 150mm front and 140mm rear on the 29er. The ride feel is very different though thanks to the improves kinematics. There is more mid-stroke support from the rear shock. This means you can pump through the trail and climb more efficiently without loosing any small bump sensitivity. The single-sided design leaves plenty of room for the modern breed of shocks with extra-large negative spring chambers. Off-the-shelf shock mounts make upgrading nice and easy.

Both the Comp Alloy and Comp Carbon get the capable performance of a Fox Float Rhythm 34 fork with a Fox DPX Performance shock. The Expert gets high-end RockShox with a Pike RC Debonair fork and a Deluxe RT3 rear shock. At the top of the range the S-Works Stumpjumper features Fox Factory suspension. With the bigger hitting ability of a 36 fork up front and a DPX2 the S-Works is even more capable on challenging terrain.

Wide bars and short stems

As for the Stumpy’s handling, the overall feel is one of balance and ease of use. It doesn’t feel big, but it motors along at pace over rough terrain with a tonne of stability. Singletrack

The new Stumpjumper is perfectly set up for attacking those rowdy trails. Wide handle bars, short stems and longer stroke dropper posts are just what you need on challenging terrain. An interesting new feature is the chainstay protector with its row of raised nubs. These act to dampen chain-slap and are surprisingly effective. On test rides, Tredz staff have commented that this the quietest bike they’ve every ridden! Making life more convenient on the trail all the carbon bikes get an integrated multi-tool.

You get a one-by drivetrain on every Stumpjumper. The both the Comp models get a Shimano XT/SLX 1x11 speed drivetrain with a wide range cassette. The other bikes all get the massive 500% gear range of SRAM Eagle 1x12 speed. GX Eagle is fitted to the Expert while the S-Works get top-of-the-range XX1 Eagle. All bikes get hydraulic disc brakes with large 200mm rotors up front for more powerful stopping. Another nice touch on the carbon bikes are the full tubes that allow hassle free cable replacement.

Specialized Stumpjumper Wheels


Wider 2.6” tyres for both wheel sizes

You get the choice of either 27.5” or 29” wheels on every model specification level. Wide 2.6” tyres are fitted on both wheel sizes. This is another much praised feature of the new Stumpy. You get a huge tyre footprint, especially on the 29er. With the deep tread of the Specialized Butcher front tyre, you get masses of grip with predictable handling on all sorts of terrain.

The Roval Traverse wheels on each bike are quality offerings with wide rims. These offer great support for the tyres, so they don’t roll even when running low pressures. The Carbon rims on the Expert and S-Works bikes combine lightweight with a slightly wider rim for even better tyre support. All the wheels are ready taped and supplied with valves, so you can set the bike up tubeless straight out of the box.

The 2.6in Specialized tyres must also be commended for their thoroughly impressive traction, with the new Gripton-equipped Butcher in particular having saved my bacon on several occasions – Singletrack

Specialized Stumpjumper

Best for

Blurs the line between trail bike and enduro bike.

The Stumpjumper is nimble on tight tracks, but also stable and confidence inspiring at high speed. Unlike bigger enduro bikes, the Stumpy accelerates quickly yet carries speed over rough sections better than most other trail bikes. Fast and fun on flow trails, yet confident in the rough, this is a bike that offers the best of both worlds.

An ideal everyday trail bike, the Stumpjumper is lightweight enough for cross-country adventures. At the other end of the spectrum this is a bike that can take on challenging enduro trails and bike park tracks. Most at home at the trail centre, the Stumpy will give you an ear-to-ear-grin on every track you ride, from blue right through to black.
