The GT Men's Aggressor Pro Mountain Bike is the answer for rocky terrain, winding singletracks, and anything else that comes your way on the dirt trails. Constructed with a 6061-T6 Aluminum Triple Triangle Frame and a SR Suntour XCT fork, the Aggressor Pro delivers optimal durability and handling. Easily transition through different elevations with the Shimano drivetrain and 8-speed shifter. This bike has never been used, just put in the car and brought home. It has a very nice cyan blue color. The frame size is 17 inches. The wheel size is 27.5 inches. It retails for $670 but I am asking for $450. Do not be afraid to ask me any questions!
