Season:2026

Brand:Specialized

The legendary Specialized Rockhopper returns, reimagined with more performance, more control, and more value than ever. Built around Specialized’s renowned Premium A1 Aluminium frame, the Rockhopper Hardtail Mountain Bike delivers the perfect blend of lightweight agility, trail-tuned handling, and modern geometry, making it the ultimate all-rounder for XC riders, trail enthusiasts, and adventure explorers alike.

Designed to offer unmatched performance at an unbeatable price, the new Rockhopper combines size-specific wheel sizing, precision-tuned suspension, and a durable Shimano 2x9 drivetrain to create a mountain bike that climbs efficiently, descends confidently, and feels incredible on every ride.


Trail-Ready Performance Meets Lightweight Durability

At the core of the Specialized Rockhopper is a Premium A1 butted aluminium frame, engineered with hydroformed top and down tubes for reduced weight and increased stiffness. This advanced frame design improves standover clearance, enhances control, and keeps you in the perfect riding position whether you’re tackling steep climbs, fast descents, or technical singletrack.

With internal cable routing for a clean, modern look and dropper-post compatibility for future upgrades, the Rockhopper delivers true trail-ready versatility without compromise.


Custom-Tuned Suspension for Every Rider

Specialized’s size-specific Rx Tune suspension technology ensures every Rockhopper frame performs flawlessly, regardless of rider size or terrain. The SR Suntour XCM fork with Multi-Circuit damping provides smooth, controlled travel across all frame sizes, maintaining consistent geometry and confident handling on rough trails.

Whether you’re shredding local XC loops or exploring backcountry routes, the Rockhopper’s suspension delivers planted stability, efficient climbing, and predictable control.


Reliable Shimano 2x9 Drivetrain & Powerful Hydraulic Brakes

A Shimano 2x9-speed drivetrain gives you precise, reliable shifting and a wide gear range for climbing steep hills or sprinting on the flats. Combined with Shimano hydraulic disc brakes, you’ll experience powerful, consistent braking performance in all weather and terrain conditions, confidence you can count on, from fast descents to technical switchbacks.


Optimised Wheel Sizing for Every Frame

To deliver the best fit and handling for every rider, each Rockhopper frame size is paired with the optimal wheel size, ensuring agility, comfort, and control across the range. From nimble 27.5” setups for smaller frames to fast-rolling 29” wheels for larger riders, Specialized’s Smart Wheel Sizing guarantees balanced handling and efficient power transfer for everyone.

The Formula hubs and 25mm internal-width rims create a wheelset that’s lightweight, strong, and durable, built to handle aggressive trail riding season after season.
