At first glance, it is difficult to understand why the Specialized Stumpjumper Comp Alloy is 600 to 900 euros more expensive than the other test candidates. It certainly can't be down to the Fox fork with its favourable Rhythm damping and the low-bandwidth drivetrain. Nevertheless, the expensive Stumpjumper pays for itself on the climbs: it pedals up the hill really well.
The long top tube and 55-millimetre stem give you a sporty, stretched-out position. With plenty of pressure on the front wheel and long chainstays, even steep ramps are no problem. The rear suspension shows hardly any signs of bobbing and the tyres roll quickly.
Downhill, the Stumpjumper benefits from the extremely short seat tube. This leaves plenty of room to manoeuvre above the low saddle. Despite the long rear end, the bike is easy to control in tight, technical sections. Subjectively, it offers the most fun on the trail in the test field. Only on the rear wheel does the Specialized require a lot of effort.
In demanding terrain, the lower travel reserves compared to the competition are particularly evident on the fork. On big hits, the suspension feels more like that of a trail bike than a potent all-mountain bike. Nevertheless, the Stumpjumper feels planted on the trail at high speeds. However, heavier riders will feel the reduced stiffness of the Fox fork with its 34-millimetre stanchions and miss the power of the Sram G2 brakes.
Overall, the comparatively light bike (14.8 kg) offers a good compromise between smoothness, agility and touring suitability. Measured by the equipment, however, the Americans have to pay dearly for this.
