The Rockhopper Expert 29 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 features Boost™ QR 141 spacing, internal cable routing, and optimized tube shapes that save weight and give clean lines to 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.
