The GT® Adult Aggressor Pro Mountain Bike enjoys an excellent development in rocky trails, bumpy roads and any other thing that may apppear on the way. It's built with a 6061-T6 Aluminium Triple Triangle Frame and a SR Suntour XCT fork. This Agressor Pro is built to last, offering a superb handling and durability. While riding, you might find different elevation levels, but this won't be a problem for the Shimano drivetrain and the 8-speed shifter integrated within the bike.
