Strengths of the Specialized Stumpjumper 15 Comp

GENIE Technology – Revolutionary Suspension

The Stumpjumper 15 is the first trail bike equipped with GENIE, a patented air spring that combines the sensitivity and control of a coil spring with the progression and lightness of an air spring.

• 39% less bottom out compared to traditional air springs

• 57% more traction compared to standard shocks

• 16.3% better impact force management

Extreme Control, Coil Feel, Air Progression

GENIE uses a two-stage compression curve: linear in the initial part and progressive in the last 30% of the travel, offering superior control on technical trails and great comfort even on the hardest impacts.

Optimized Trail Geometry

Designed to dominate downhill, stay agile on technical sections, and climb efficiently.
