All barn-burner and no benchwarmer, the Specialized Rockhopper Sport 29 Aluminum 9 Speed Front Suspension Mountain Bike throws out the playbook when it comes to putting performance points on the board while playing some serious defense on behalf of your wallet.

Game-ready with Tektro M275 hydraulic disc brakes, Shimano Atlus shifting and an SR SunTour XCM fork that’s built to hustle, the Specialized Rockhopper Sport can tack up the win on any given Sunday—and the rest of the week too for that matter.

• A heart of gold, presented in our lightweight yet durable Premium A1 Aluminum, the Rockhopper’s butted aluminum frame features hydroformed top and downtubes to keep weight low and strength high, all while providing increased standover clearance, slick internal cable routing, and dropper-post compatibility.

• To ensure 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 Specialized's 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.

• Beautifully beastly, Tektro hydraulic disc brakes pack a mean bite but deliver their power with a refined, intuitive feel to make for a package that punches way above its pay grade.

• Keep things simple with a durable Shimano drivetrain with plenty of range and a clutch-equipped rear derailleur that keeps your ride quiet—and your chain on.

• Pair dead-reliable hubs from Formula with Specialized's 25-millimeter internal diameter, hookless Stout rims for a strong, light, and durable wheelset hat trick.
