Specialized Rockhopper Comp
Product Details
The Specialized Rockhopper Comp 27.5 is built for big adventures and bigger thrills. With a lightweight yet tough Premium A1 Aluminum frame, this hardtail is ready to rip through singletrack with speed and confidence. The frame features hydroformed tubing to keep the weight down and the strength up, while internal cable routing and dropper-post compatibility give it a clean, future-ready setup. Each frame size is paired with the ideal wheel size to give every rider the best fit and handling possible.
Up front, a RockShox Judy fork smooths out rough trails, while Shimano BR-MT200 hydraulic disc brakes deliver strong, consistent stopping power. The wide-range Shimano 1x12 drivetrain offers simple shifting and a clutch-equipped rear derailleur to keep your chain quiet and secure. Rounding out the build is a tough Specialized alloy wheelset with reliable Formula hubs and hookless rims designed to take a beating without slowing you down. Whether you're chasing your first trail ride or pushing the limits on weekend loops, the Rockhopper Comp is ready to roll.
