Riding Three Years of Stumpjumper 15 and GENIE Shock Development in Two Days 2

There was a lot of discussion about WHY they made the changes they did, how the shock actually works, and how it coexists with the new Stumpy. We had many of the same questions. So we went to Auburn, California, to get the answers.
