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.
This Rockhopper comes spec'd with a mix of durable Shimano components, powerful Shimano hydraulic disc brakes, a grippy Ground Control front tire and Fast Trak at the rear, and an SR Suntour XCR-Air fork with just the right amount of travel.
- The frame is constructed from lightweight A1 SL Aluminum in order to provide a compliant, durable platform to support our acclaimed XC Sport 29 Geometry. Combined, you get a bike that's more than efficient on climbs and descends just as well.
- SR Suntour XCR-Air fork features 80/90/100mm (size-specific) of suspension travel that swings well above its weight class.
- Shimano Deore rear derailleur provides crisp, reliable shifting that you can count on when the going gets rough. With it, you'll be able to precisely move through the wide gear range to make cruising the flats almost as easy climbing those hills.
