Specialized Stumpjumper 15 Comp Alloy: The Ultimate Trail Bike Obliterator

The SPECIALIZED STUMPJUMPER 15 COMP ALLOY is here to obliterate every trade-off in the trail game. It devours bumps like a big bike. It still provides short-travel control, playfulness, and efficiency. Consequently, this bike handles the toughest trails. It’s the ultimate Mountain Bike for dedicated Cycling in Dubai.

Breakthrough Capability with GENIE Shock Technology

The biggest innovation on the Stumpjumper 15 Comp Alloy is GENIE. Specifically, this patent-pending air spring technology grants every trail rider three wishes:

1. Maximum grip and traction (like a coil spring).
2. Better bottom-out prevention (than a standard air spring).
3. The ability to tune mid-stroke and end-stroke support independently.

The Magic Carpet Ride

GENIE combines two concepts. It uses the control-enhancing linear spring rate of a coil spring through the “bump zone.” Then, it switches to the progressive spring rate of an air spring at the end of the stroke to avoid bottom-outs. Truly, it’s the best of both worlds—coil and air—with extra tunability.

• What Bump?: GENIE provides $16.3\%$ better bump force management than a traditional air-sprung shock. Consequently, the Stumpjumper $15$ Comp Alloy rides like a bike with more travel. For example, both the Stumpjumper $15$ Comp Alloy ($145\text{mm}$ rear travel) and our Enduro ($170\text{mm}$ travel) use $101\text{mm}$ of travel. This allows them to absorb a $1080\text{ N}$ bump force.
• Traction Galore: Extensive field testing proves the Stumpjumper $15$ Comp Alloy delivers $57\%$ better traction with GENIE. This is because GENIE offers supple, coil-like performance. It keeps the wheel in contact with the ground a greater percent of the time.
• Bye, Bye, Bottom-Outs: You benefit from the rising rate in the last $30\%$ of the GENIE stroke. Thus, it results in $39\%$ fewer bottom-outs than a standard air spring.

Honed Geometry and Unmatched Personalization

This bike’s geometry delivers big bike capability when you need it. It provides a nimble feel in tight sections and lively, efficient climbing manners.

• Honed Geometry: The generous cockpit centers you on the bike, optimizing traction and corner control. Furthermore, the low bottom bracket, slack head tube angle, and optimized fork offset keep things stable in the rough.
• Ride Your Way: The Stumpjumper $15$ Comp Alloy seamlessly integrates benchmark geo adjustability. Ultimately, this makes it the most personalizable trail bike ever. Six distinct geometry settings allow you to hone performance for any style or terrain.
• Wheel Choice: Our aftermarket shock links let you choose between 29′′ wheels front and rear. Alternatively, you can use a mixed wheel setup (27.5′′ rear) for a responsive and playful ride.
• Carry It All: SWAT on the Stumpjumper $15$ Comp Alloy elevates downtube storage, an innovation we pioneered.
