Stumpjumper Expert

With the all-new Stumpjumper Expert, we've bottled up that "new bike day" feeling and put it into a radical new trail bike so agile, so lively, so in-tune with the trail, that it feels like an extension of your body. Levitate up the climbs. Decimate the descents. The Stumpjumper Expert is going to make you rethink how a trail bike should ride.
