The GT Aggressor Expert is an agile hardtail that will help you ride like an expert from day one. This bike could be your everyday bike to go from the trails to your local bike paths and everywhere in between. I tall starts with then lightweight 6061 alloy frame with floating seat stays which 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 XCM-DS fork with 80mm travel can handle some of the rougher trails in relative comfort. But the Tektro M275 Hydraulic 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 components, including microSHIFT front and rear derailleurs, shifters and cassette. It all adds up to a reliable recreational mountain bike with components and design that will last for hours of fun on the trails.
