If you only analyse the lab data of the Specialized Stumpjumper EVO S-Works, only the slightly shorter fork travel tells you that this is not a true enduro bike. The 64-degree head angle, an extremely low bottom bracket and the high front end, on the other hand, fit perfectly into this comparison. The chainstays are even the longest at 443 millimetres.
These geometry dimensions place the rider low and secure on the bike and ensure stable directional stability. This allows the Stumpjumper EVO to inspire downhill with a lot of confidence on fast tracks. In tight corners, the long rear end requires a little more physical effort than the more compact bike Pivot Firebird Team.
However, when the going gets really rough, the Stumpjumper stands out among the thoroughbred enduro bikes. The suspension responds well, but is firmer and less skilful at digesting big lumps than the suspension of the competition. On the one hand, this is due to the limited damping qualities of the slimmer 160 mm fork, on the other hand, the smaller Float-X shock - compared to the X2 models from Pivot and Yeti - lacks damping control. On the other hand, the Stumpjumper catapults itself over off-road edges with plenty of pop and ease and generates plenty of speed on undulating terrain.
Speaking of light: with a total weight of just 14.4 kilos, the Specialized is the best value in this comparison. The foundation for the refreshingly light overall package is laid by the carbon chassis, which weighs just 2344 grams. For comparison: Canyon and Yeti weigh almost 800 grams more. But the 36 mm Fox fork also saves around 360 grams compared to the models with 38 mm stanchions.
The elegant carbon wheels also contribute to the good weight balance. Coupled with its rocker-free rear triangle, the Specialized leaves the competition far behind in the uphill rankings, even without having to switch the platform lever on the shock. Also good: The Specialized cuts a fine figure on long tours thanks to its pleasantly sporty riding position.
Conclusion on the Specialised Stumpjumper EVO S-Works on test 2023
The Specialized Stumpjumper EVO S-Works is actually a class below the other enduro bikes in this test and offers the least reserves on rough trails. On the other hand, it climbs better than the competition and remains competitive on downhills thanks to its downhill-focussed geometry. - Thomas Weschta, BIKE test rider
