    The Specialized Rockhopper Comp 27.5" Mountain Bike: the Hollywood blockbuster of summer adventure rides! This bike craves action and thrives on thrilling twists and turns, thanks to its all-new, Premium A1 Aluminum frame, making it a trail sensation!

    So, get ready for a wild adventure with the Specialized Rockhopper Comp 27.5" Mountain Bike - it's a show you won't want to miss! Roll the credits and hit the trails like a true biking superstar!

    Features:

    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 lockout-equipped 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, SRAM Level 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 1x MicroSHIFT drivetrain that offers plenty of range along with a clutch-equipped rear derailleur that keeps your ride quite-and your chain on.

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