The Specialized Stumpjumper EVO is the underdog in this group test. It has comparatively little travel but tries to compensate for this deficit with its extreme geometry. We were curious to see how the concept performs and how the bike would fare against the competition.

Specialized Stumpjumper EVO Comp Alloy 29 | € 3,499 | 150/140 mm (f/r) | 15.22 kg | 29″

When it comes to geometry, the Stumpjumper is the most radical bike in the test. It has a super slack 63.5° head angle, a very low bottom bracket and long reach. However, Specialized combines these values with only 140 mm travel on the rear and a 150 mm FOX 36 FLOAT Rhythm fork up front. The remaining spec of the € 3,499 bike is trimmed towards downhill performance. The SRAM CODE R brakes, Specialized Butcher GRID tires and the cockpit consisting of an 800 mm handlebar and 40 mm stem all confirm that this bike is not about winning hill climb competitions. The Stumpjumper EVO has the same asymmetric bridge between the top and the seat tube as the regular Stumpy, designed to provide optimal stiffness. There is a flip-chip on the lower shock mount with which you can adjust the head and seat tube angles by 0.5° and change the bottom bracket height by 6 mm. The bike is available in only two sizes and we opted the longer S3 option.

The steeper the better! The Stumpjumper EVO is made for steep descents.

Limited
Specialized only offer the Stumpjumper EVO in two sizes. Instead of M and L they are called S2 and S3 and are based on the length of the bike.
Linear
The rear suspension of the Specialized Stumpjumper doesn’t suit its progressive geometry. It uses up the available travel too readily and only offers a moderate amount of progression. As a result, it quickly reaches its limits in rough terrain – but this is exactly where the geometry shines.
Solid
The X-Fusion Manic dropper post performed convincingly over the entire test period. We actually prefer it over the Specialized Command Post featured on the more expensive models.
Well silenced
The chainstay guard effectively dampens chain slap on other Specialized models. However, it gets overwhelmed at higher speeds, causing the bike to rattle audibly. We heard the chain slapping the chainstays several times.

The Specialized Stumpjumper EVO Comp Alloy 29 in review

As you ride it, you’ll immediately notice that this is not your run-of-the-mill trail bike. Due to the super-slack head angle in the low setting, the front wheel tends to topple from one side to the other on the climbs. You’ll find it worth reaching for the compression lever on the shock to suppress any bob at the rear. Due to the very low bottom bracket, you’ll also have to be careful of pedals strikes on more technical terrain. Overall, the Specialized Stumpjumper EVO is a capable climber, but its short travel doesn’t make it climb more efficiently than the best bikes in the test. After a few rides, we switched to the steeper and higher geometry setting as the front wheel felt somewhat unstable even on the descents. In the higher setting, the handling is more balanced and controlled, though the geometry remains aggressive.

Tuning tip: volume spacer in the shock | more robust tires | choose the high setting!

The slack head angle, the bike’s length and the low slung top tube mean that the Stumpjumper EVO instils you with the confidence to keep pushing a little harder and going a little faster. Unfortunately, the suspension can’t always keep up. The linearly tuned 140 mm travel quickly gets overwhelmed by bigger hits and passes the blows onto the rider, requiring you to get back on the brakes. Cornering, the Stumpjumper handles well in the high setting, though it needs an active riding style in flat sections and requires a lot of input from the rider when things get tight.

Unfortunately, once the geometry comes into its own, the suspension is already at its limit!

Conclusion

The Specialized Stumpjumper EVO is a very unique bike for a very unique type of rider. If you tend to ride steep trails that aren’t all that demanding or rough, this is a great choice, offering extremely agile and lively handling thanks to the short travel suspension. But as soon as you push it too hard, the suspension will let you know.
