GT Aggressor Sport.
The Aggressor Sport is the entry-point model in the Aggressor series.
The Sport has the following features:
- 7-speed gear system.
- Mechanical disc brakes.
- Aluminium frame
GT Aggressor Pro.
For a similar price, if you can go the Aggressor Pro it's definitely worth it:
- 8-speed gears use upgraded components.
- Slightly better mechanical disc brakes.
The 8-speed setup translates into smoother gear changes.
GT Aggressor Expert.
The Aggressor Expert is the top of the range option:
- 8-speed gears.
- Hydraulic disc brakes (instead of mechanical disc).
- Better front suspension.
- Better frame.
The Expert's hydraulic disc brakes means less maintenance, more power and control.
Another option? Haro Flightline Two.
Yes, the Flightline Two is definitely worth considering and it's comparable to the Aggressor Pro.
We place it here because Haro's frames are exceptionally well made. Like the Aggressor Pro, the Flightline Two has:
- An 8-speed gear system.
- Mechanical disc brakes.
The Flightline Two uses intern cables which makes the bike look cleaner. Also comes in matte black.
