The Specialized Rockhopper Comp 29" Mountain Bike - the summer blockbuster of mountain bikes that's all about adrenaline-pumping adventures and thrilling plot twists! This bike is equipped with an all-new, Premium A1 Aluminum frame, ready to make its mark on any singletrack.
The Specialized Rockhopper Comp 29er is the star of the show, combining heart-racing action, top-notch performance, and a stellar supporting cast. Get ready to roll on the best-handling wheel for your frame size and embark on the ultimate biking adventure with the Rockhopper Comp 29er!
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.
