Specialized Rockhopper – Better Performance, Better Value
The Rockhopper delivers top-tier performance without breaking the bank. By pairing each rider with their ideal wheel size and suspension tuned for every frame size thanks to our size-specific Rx Tune, we’ve baked in extra performance while keeping the price right.
Lightweight & Durable Frame
The Premium A1 Aluminum butted frame is hydroformed for low weight and high strength, with increased standover clearance, internal cable routing, and dropper-post compatibility. Each size is paired with the best wheel for fit and handling, ensuring a perfect ride for every rider.
Suspension & Handling
The SR Suntour XCM fork with custom Multi-Circuit damping delivers size-specific travel and spring rates, ensuring consistent geometry, handling, and suspension performance no matter the frame or wheel size.
Drivetrain & Brakes
A crisp and reliable Shimano 2x9 drivetrain provides smooth shifting for any terrain, while Shimano hydraulic disc brakes deliver confident stopping power with intuitive control.
Wheels & Tires
Durable Formula hubs paired with 25mm internal-width rims create a strong, lightweight, and durable wheelset, giving you confidence on every ride.
