Specialized Rockhopper Comp Mountain Bike
Hit the trails on the Specialized Rockhopper Comp Mountain Bike; pairing the latest A1 aluminium frame to a SR SunTour XCM fork with lockout function, you get low weight, high durability, impressive handling and a fast, fun ride. Not only does this bike ride well, but it looks good too, with internal cable routing adding a slick finish. The wheels supplied are frame-size specific, as are the travel and spring rates, ensuring there are no compromises for any rider.
SRAM Level hydraulic disc brakes take on stopping duties, delivering reliable power in all conditions and across all terrains, while a clutch-equipped microSHIFT drivetrain in a 1x configuration makes shifting quiet and fast and reducing the chances of chain drop. The wheels have Formula hubs and hookless Stout rims and are built for strength and durability while keeping weight down.
Highlights
- Lightweight yet durable premium A1 aluminium 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, 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
- The lockout-equipped SR Suntour XCM with custom Multi-Circuit damping has size-specific travel and spring rates
- 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
- Durable 1x microSHIFT drivetrain offers plenty of range along with a clutch-equipped rear derailleur that keeps your ride quiet and your chain on
- Reliable hubs from Formula are paired with 25mm internal diameter, hookless Stout rims for a wheelset hat-trick: strong, light and durable
