GT's Aggressor Comp is up for adventure. With a nimble, stiff GT 6061-aluminum Triple-Triangle frame, a bump-absorbing All Terra suspension fork, and a wide-range 21-speed Shimano drivetrain, you have all the tools necessary to tackle rolling terrain on and off road. Meanwhile, the 27.5-inch aluminum wheels make the going easy, while the Tektro disc brakes and versatile tires provide confidence and control.
