Specialized Rockhopper Expert Mountain Bike 2023
Balancing value and performance perfectly, the Specialized Rockhopper Expert Mountain Bike is a highly capable and efficient choice for a range of off-road terrain. At the core is a premium A1 alloy frame with hydroformed tubes to keep weight low and strength high, and it is dropper post compatible and routes all cables internally for a slick look. This frame is paired with a RockShox Judy SoloAir fork with TurnKey lockout that has frame size-specific travel to bring the same shock absorption and handling to every rider. The tubeless-ready wheels and tyres are also optimised for the frame size, supplied in either 27.5" or 29".
The bike is built up with SRAM components; SRAM SX Eagle makes up the drivetrain in a 1x12-speed configuration with a wide-ranging cassette, and SRAM Level brakes deliver powerful all-condition stopping. Finishing kit includes a Specialized Bridge Sport saddle and Stout Mini Rise alloy handlebar.
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
- RockShox Judy SoloAir fork with TurnKey damper lockout brings air-sprung sensitivity and performance
- SRAM SX Eagle 1x12 drivetrain and SRAM Level hydraulic disc brakes
- Tubeless-ready rims and tyres
