The GT Aggressor Sport is an extremely versatile 27.5 inch hardtail mountain bike that is built to take you from the town to the trails. The Aggressor Sport brings capable handling and comfortable, confidence-inspiring performance to the table. The 6061-T6 Aluminum Triple Triangle™ Frame is the basis for the durability and reliable performance the Aggressor Sport offers. The trusty frame is powered by a 21-speed Shimano Drivetrain, with enough range to help you up the steepest ascents and descents. The SR Suntour fork with 75mm travel will help you tackle the bumps and then when you’re flying down hill you’ll need some assistance to stop. This is where the mechanical disc brakes will give you reliable stopping power regardless of the conditions.

The GT Aggressor Sport is an entry-level hardtail mountain bike that can help you commute on weekdays and hit the trails on the weekends, you really can do what you like. The Aggressor Sport is a reliable mountain bike that gives you everything you need to get started at an affordable price.
