Giant ATX 27.5 Hardtail Mountain Bike

A highly versatile entry-level hardtail mountain bike engineered with a lightweight ALUXX aluminum frame, a bump-smoothing front suspension fork, and agile 27.5-inch wheels built for confident trail tracking and off-road exploration.

Key Highlights

• Proprietary ALUXX Aluminum Mountain Chassis: Handcrafted from premium 6061-series raw alloy material in Giant’s dedicated forging facilities. Delivers a highly durable, lightweight frame profile with trail-tested geometry for robust handling.

• Smooth-Damping Front Suspension Fork: Outfitted with a responsive front suspension fork. Engineered to effortlessly absorb sudden root impacts, loose gravel trail chatter, and potholes to reduce rider fatigue over longer distances.

• Versatile 21-Speed Shimano Gearing: Driven by a durable 21-speed (3×7) Shimano gear matrix. The triple-chainring layout provides a highly practical, wide range of gear ratios to handle steep singletrack climbs and flat fire roads with equal efficiency.

• High-Volume 27.5-Inch Wheel Platform: Features agile, fast-rolling double-wall alloy rims wrapped in wide mountain tires. This design creates a larger tire contact patch for superior tracking stability, shock absorption, and cornering grip on loose dirt.

• Integrated Trail Architecture & Routing: Built with internal frame ports that hide mechanical shifting cables for a premium aesthetic, paired with factory-reinforced eyelets for simple installation of aftermarket accessories like mudguards or rear storage racks.
