2022 GT Aggressor Expert review

Jun 2022

The GT Aggressor Expert is the top end bike in the Aggressor range that’s built for recreational off-roaders who want the best in value. With that in mind, the brand has done a solid job of the bike’s spec and geometry, making it a bike that’s welcoming, capable and comfortable enough for entry-level singletrack jaunts. The best mountain bikes for under £600 - our top picks 2022 Voodoo Bizango review Best MTB's that you can get shipped straight to your door GT’s Aggressor Expert is built around an alloy frame that employs the brand’s simple but rather clever Triple Triangle design.

GT Aggressor Sport review - MBR

Jun 2019 · Jamie Darlow

With an excellent four sizes in the range the GT Aggressor Sport should suit pretty much every rider’s size, lanky old me included.

Highs
  • Classic frame, decent brakes and good tyres backing them up

Lows
  • Small sizing, poor performing fork and ghost shifting
