The GT Aggressor Expert hardtail mountain bike is ideal for the recreational rider that wants to get out and explore their local trails. The Aggressor is built with a high-quality 6061 alloy frame which is lightweight and durable so that you can have confidence in your ride. The floating seat stays improve comfort so you can spend more time in the saddle and enjoy the Aggressor on longer rides. GT built his bike for off-road use but it's also a capable commuter rolling on the fast WTB Ranger Comp tyres and WTB SX19 rims.

While the SR Suntour M3030 fork can handle some of the rougher trails in relative comfort. The cable actuated mechanical disc disc brakes really are the standout on the Aggressor, offering excellent stopping power on any trails and in any conditions. GT equipped this bike with a range of high-quality Shimano components, including front and rear derailleurs, as well as Shimano EZ Fire EF41 shifters. The GT Aggressor Expert is a reliable recreational mountain bike with components and design that will last.


  • Now with blended wheel-size accommodates a wide range of riders XS,S (27.5"), M,L,XL(29")
  • Floating seat stays provide a more comfortable ride
  • Rack and fender ready delivers max utility
  • All new 6061 alloy triple triangle frame design.
