Specialized Rockhopper Sport – Hardtail Mountain Bike at Bike Attack Santa Monica

Affordable Performance for Trails, Fitness, and Everyday Riding

The Specialized Rockhopper Sport is a lightweight, durable, and capable hardtail mountain bike built for riders who want dependable trail performance without exceeding their budget. Available at Bike Attack Santa Monica, the Rockhopper Sport combines a premium aluminum frame, responsive front suspension, Shimano hydraulic disc brakes, and a simple Shimano 1x drivetrain.

Whether you are exploring local trails, improving your fitness, riding through the city, or purchasing your first mountain bike, the Specialized Rockhopper Sport delivers confident handling and reliable performance.

Lightweight Specialized A1 Premium Aluminum Frame

At the heart of the Rockhopper Sport is Specialized’s lightweight and durable A1 Premium Aluminum frame. Hydroformed and butted aluminum tubing helps reduce unnecessary weight while maintaining the strength needed for off-road riding.

The frame also features:

• Increased standover clearance for easier mounting and improved rider confidence
• Clean internal cable routing
• Dropper-post compatibility for future upgrades
• Trail-ready geometry designed for stability and responsive handling
• Multiple frame sizes to help riders find a comfortable, efficient fit

SR Suntour XCM Suspension Fork with Specialized Rx Tune

The SR Suntour XCM suspension fork helps absorb bumps, roots, rocks, and uneven terrain for a smoother and more controlled ride.

Specialized’s Rx Tune uses size-specific suspension travel and spring rates to provide consistent geometry, handling, and suspension performance across the Rockhopper size range. The fork also includes a lockout function, allowing riders to reduce suspension movement while climbing or riding on smoother pavement.

Shimano Hydraulic Disc Brakes

Shimano BR-MT200 hydraulic disc brakes provide strong, consistent, and easy-to-control stopping power. Their smooth lever feel makes it easier to manage speed confidently on steep descents, loose trails, wet roads, and busy city streets.

These reliable hydraulic brakes give the Specialized Rockhopper Sport braking performance that exceeds expectations for a mountain bike in its price category.

Durable Shimano CUES 1x Drivetrain

The Rockhopper Sport keeps shifting simple with a durable Shimano CUES 1x drivetrain.

The single front chainring eliminates the complexity of a front derailleur while still providing a useful range of gears for climbing hills, navigating trails, and maintaining speed on flatter terrain. Shimano CUES components are designed for dependable shifting and long-term durability.

Strong Specialized and Formula Wheelset

Formula hubs are paired with Specialized rims featuring a 25 mm internal width. This combination creates a wheelset that is strong, lightweight, and durable enough for recreational mountain biking, fitness riding, and everyday use.

The wider rims also provide a stable tire profile for improved traction and control on varied terrain.

29-Inch Wheels for Confident Trail Performance

The Specialized Rockhopper Sport is equipped exclusively with 29-inch wheels. The larger wheel diameter rolls smoothly over rocks, roots, potholes, and uneven terrain while providing excellent stability, traction, and momentum.

Paired with wide Specialized Ground Control 29 x 2.35-inch T5 tires, the Rockhopper Sport delivers confident handling on dirt trails, gravel paths, fire roads, and city streets.
