2018 Men's Rockhopper Expert

The Rockhopper Expert is the perfect bike to begin your dive into the XC world. That's because we built it to be light, durable, and exceedingly capable, but how we did it is almost as fun as riding it.

It starts with our new A1 SL alloy frame that has optimized tube shapes which save weight while dramatically improving aesthetics. To go along with these clean new lines, the new Rockhopper also has internal cable routing to further clean up the frame. Lastly, our Sport XC 29 geometry adjusts the reach, angles, and standover height to make for an improved fit across the size range. This is sure to keep you ripping and confident while heading both up and down the trail.

This Rockhopper comes spec'd with a mix of durable Shimano components, powerful Shimano hydraulic disc brakes, grippy Ground Control tires, and an SR Suntour XCR-Air fork with just the right amount of travel.

Sure

I had a Giant before I bought this bike. I wasn't very excited about my Giant. But as soon as I traded in the Giant for this one and began to use it on the dirt trails near my hhome I fell in love with this bike..
