A bike with lower gearing will be easier to ride up steep hills, while a higher top end means it will pedal faster down hills.

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
