The Specialized Stumpjumper was the first bike Specialized ever released in 1981, and it’s come a long way since then. The Stumpjumper is made for trail riding at its best, with a versatile and accessible riding characteristic that allows anyone to jump on and feel right at home. The Stumpjumper is that one bike that’ll get you easily to the top of any climb, while making sure a smile is never far away on the way down.

Specialized offer the Stumpjumper in both 27.5” and 29er models too, giving you the option of finding a bike that suits you perfectly. We review the whole Specialized Stumpjumper range of models that feature either RockShox, Fox or Öhlins suspension and a flagship S-Works model that pushes the limits of style and purpose.

Specialized Stumpjumper frame


SWAT downtube storage

Specialized have developed and honed their FSR suspension design for decades, and it’s on the Stumpjumper that you can see this the best. The Stumpjumper is available with a few different frames, though they all share the same proven geometry. The Stumpjumper Comp Alloy comes with an M5 alloy frame, while the Comp Carbon and Expert Carbon have FACT 9m carbon front triangles and M5 swingarms. The S-Works gets a full FACT 11m carbon frame, which makes it even lighter and stiffer.

Every model comes in both 29er and 650b (27.5”) guise, giving you the option that suits your riding style best. Every carbon model from the Comp Carbon all the way to the S-Works gets a SWAT storage system on the downtube, allowing you to take the weight off your back and keep your essential items safely stored away. Internal cable routing and downtube protection keeps the frames safe and neat.

Specialized’s Stumpjumper has always been a mainstay in their range, delivering versatile and capable performance on a wide range of riding conditions and terrain

Specialized Stumpejumper suspension


FSR suspension at its best

With 135mm or 150mm rear travel, the Stumpjumper is poised to be the perfect do-it-all trail bike, with the ability to tackle both local trails and enduro races

Specialized can do no wrong with their FSR Horst link rear suspension design. It’s featured throughout their range, yet makes its most versatile appearance in the Stumpjumper range. The 650b Stumpjumper has a full 150mm travel in the rear, mirroring many enduro bikes, while the 29er model gets 135mm travel. Both models are hugely capable, taking on challenging trails with ease.

Every model gets a 150mm fork, no matter the wheel size, so the front end is a similar height, giving a balanced ride throughout the range. The alloy and carbon Comp models both get RockShox forks, while the Carbon Expert has a Fox 34 up front. Throughout the range, you’ll find RockShox Monarch rear shocks. The only exception is the flagship S-Works model, which receives an Öhlins STX rear shock to match the Öhlins RXF fork up front. Every rear shock on the Stumpjumper range features Rx Trail Tune for a custom ride, as well as AUTOSAG, making setup a breeze.

SRAM 1x drivetrains across the range

Having enough gearing is not an issue that anyone on a Specialized Stumpjumper will encounter. SRAM 1x drivetrains are found on every model in the range. The use of a single chainring drivetrain also allows Specialized to have a shifter-style dropper post lever on the left side, giving a much better action than an over-bar remote.

The Stumpjumper Comp Alloy and Comp Carbon both have GX 11 speed drivetrains with wide 10-42T cassettes. For the rest of the range, SRAM’s new Eagle 12 speed drivetrains are specced, coming with a massive 10-50T cassette. These easily match the range of a double chainring drivetrain. SRAM Guide 4-piston disc brakes are found across the whole range, with the S-Works getting the RSC model for ultimate adjustment. These are powerful brakes with high modulation, giving greater control of your speed.

Specialized have fully committed to single-chainring drivetrains, with their simplified shifting and greater reliability, not to mention wide gear range

Specialized Stumpjumper wheels


Roval Traverse wheels

Roval Traverse wheels give a great platform for the tyres, with an ideal inner width to take anywhere from 2.3” to 3.0” tyres.

Each model in the Specialized Stumpjumper range comes in either 29/6Fattie or 650b guise. The 29/6Fattie bikes come with 29er wheels with 2.3” tyres and the option of using 650+ wheels should you want. The 650b models get 27.5” wheels and large 2.6” tyres. The larger wheels do well to make up the travel difference between the 650b and 29er models, being able to roll easier over large objects.

Specialized’s Roval Traverse wheels adorn each model, coming with a 30mm inner width, giving the tyres greater stability. On the Expert Carbon and S-Works Stumpjumpers, carbon Traverse SL wheels are found, with quick engaging DT Swiss hubs. Both alloy and carbon comp models get alloy rimmed Traverse wheels. Specialized Butcher tyres come on every model, giving superb traction in a wide variety of conditions.
