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.
