Overview
About this bike
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 All Terra suspension fork and powered by a 21-speed Shimano drivetrain. Together, they give you the tools to tackle whatever comes rolling your way. On top of that, the 27.5-inch aluminum wheels make pedaling easy, while the mechanical disc breaks and versatile tires provide quick stopping power and great grip.
