The GT Aggressor Expert is an extremely versatile 27.5 inch hardtail mountain bike that is built to take you from the town to the trails. The Aggressor Expert brings capable handling and comfortable, confidence-inspiring performance to the table in a single package. The 6061-T6 Aluminum Triple Triangle™ Frame w/ replaceable derailleur hanger is the basis for the durability and reliable performance the Aggressor Expert offers. The trusty frame is powered by a 24-speed Shimano Drivetrain, with enough range to help you up the steepest ascents and descents. The SR Suntour XCM fork with 80mm travel will help you tackle the bumps and then when you’re flying downhill you’ll need some assistance to stop. This is where the Tektro mechanical disc brakes will give you reliable stopping power regardless of the conditions.
