Rockhopper Pro 29

2017 Rockhopper Pro 29

If you're ready to take your trail riding to the next level, let us introduce you to your new friend, the Rockhopper Pro 29. We built it to be light, durable, and exceedingly capable, but how we did it is far more interesting. It all starts with an A1 SL 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. Along these lines, we spec'd it with a mix of Shimano Deore XT and SRAM, fast-rolling Ground Control Sport tires, and a plush fork from RockShox. 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.
