Product Information

Specialized Rockhopper Sport 27.5 Mountain Bike

Maybe you're starting out and finding your legs and love for the singletrack, or perhaps you're just dirt-curious? Either way, the Rockhopper Sport 29 is ideal for both scenarios and is the only bike you need to live out your trail dreams and adventures. It places a focus on long haul performance and we're not talking about 100-mile trail rides here but lasting components that'll keep you riding strong through all the seasons of the year. Its corrosion-resistant hardware is built to last, while all of the components are purposely selected for their balance of strength and capability. And setting everything the Rockhopper Sport over the top is Specialized's Trail 29 Geometry that is guaranteed to leave you feeling planted, confident, and efficient out there on the dirt. The Rockhopper Sport features Specialized's A1 Aluminium frame that provides you with a lightweight base that offers agile handling and is designed to be durable and robust for a long-lasting frame and peace of mind out on the trails. Specialized also equipped the Rockhopper sport with 2.3" Ground Control Sport tyres so that you can have reliable traction to the trail in all weather conditions.

Full Specification



The Rockhopper

A heart of gold, presented in Specialized's lightweight yet durable Premium A1 Aluminum, the Rockhopper features butted aluminium tubes 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, Specialized has 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.


Superior Shifting 

Settle in for any climb with the Shimano Altus 9-speed drivetrain, with two chainrings and a wide-range cassette for the perfect gear on any terrain. Ergonomic Rapidfire Plus™ trigger shifters offer precise gear changes without changing your grip compromising control. A durable Formula freehub and SunRace 9-speed cassette keeps you rolling smoothly without putting up a fuss.



Specialized chose the front and rear tyres to optimise around the Rochkopper wheel’s purpose. The front and rear Ground Control Sport tyre provide aggressive side knobs that offer grippy cornering bite in varied conditions. With Rx Tune on Rockhopper, the SR Suntour XCM 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 size
