The Specialized Stumpjumper 15 Pro features a GENIE technology- a patent-pending air spring designed by the Specialized Science Club. This innovative feature allows riders to adjust their six-way geometry, choose between mixed wheel or 29" options, and customize their spring curve for optimal control and a playful ride.
