GT's Aggressor Sport is a great rig for the trails and the city. GT's 6061-aluminum Triple-Triangle frame is led by a bump-absorbing SR Suntour suspension fork and powered by a 21-speed Shimano drivetrain. Together they give your the tools to tackle whatever comes rolling your way. On top of that, the 27.5-inch aluminum wheels make pedaling easy, while the disc brakes and versatile tires provide control and great grip.
