    Rockhopper Expert 29

    2017 Rockhopper Expert 29

    If you're the one in your group that's always getting followed on the trail, the Rockhopper Expert 29 is here to make sure that it stays that way. We built it to be light, durable, and exceedingly capable, but how we did it is far more interesting. It all starts with an alloy construction that'll resist corrosion and take a beating, while the components are purposefully selected to squeeze every last drop of performance for the money. But what we're most proud of is the Rockhopper's Trail 29 Geometry. It features a low bottom bracket, roomy top tube, and short chainstays to keep you ripping and confident both up and down the trail.
