2025 Specialized Rockhopper Features
Better performance. Better value. Better Rockhopper. By tapping the fit and handling advantages of pairing each rider with their ideal wheel size and suspension that works its hardest for everyone thanks to our size-specific Rx Tune, we've baked in added performance to the Rockhopper without dialing up the price.
The reliable and crisp Shimano drivetrain provides a robust 2x9 drivetrain that can handle everything you're throw down while confident braking from Shimano hydraulic disc brakes seals the deal of the century.
At a Glance
- A heart of gold, presented in our lightweight yet durable Premium A1 Aluminum, the Rockhopper’s butted aluminum frame features hydroformed top and downtubes in order to keep weight low and strength high, all while providing increased standover clearance, slick internal cable routing and dropper-post compatibility.
- With the goal of making sure that the Rockhopper offers both the best fit and best performance for every person, no matter their measure, we’ve paired each Rockhopper frame size with the optimal wheel size. The result is a Rockhopper to fit every rider and the assurance that every Rockhopper is rolling on the best-handling wheel for its frame size.
- Bringing our Rx Tune to Rockhopper for the very first time, the SR Suntour XCM with custom Multi-Circuit damping brings size-specific travel and spring rates to the show in a performance that’s sure to impress while also ensuring consistent geometry, handling and suspension performance, regardless of frame or wheel size.
- Pair dead-reliable hubs from Formula with our 25-millimeter internal diameter, rims for a wheelset hat-trick: strong, light and durable.
