Specialized S-Works Stumpjumper 15 Frameset

The GENIE air spring is designed to provide the supple, ground-hugging feel of a coil shock while retaining the lightweight tunability and bottom-out resistance of an air spring. It effectively manages the initial stroke to improve traction and comfort without sacrificing the support needed for bigger hits.

You have the flexibility to run either a full 29-inch wheel setup or a mixed-wheel (mullet) configuration. The frame is engineered to accommodate both, allowing you to tailor the bike's handling to your preferred riding style or terrain.

The frame features six-way adjustable geometry, allowing you to fine-tune the ride characteristics to your specific needs. This includes an adjustable head angle ranging from 63 to 65.5 degrees, giving you control over how stable or responsive the bike feels on different trails.

Yes, the frame uses a threaded bottom bracket for reliability and is compatible with SRAM UDH (Universal Derailleur Hanger) components. This makes it straightforward to source parts and ensures compatibility with the latest drivetrain standards.

Specialized includes a lifetime bearing replacement program for the original owner. This covers the pivot bearings, which simplifies long-term maintenance and helps keep the suspension movement smooth over the life of the frame.
