It's right for you if...
You're a commuter or fitness rider who’s having fun spending more time in the saddle. You want a great-looking bike that's versatile, comfortable and built with quality parts that will perform on longer rides.
The tech you get
A lightweight aluminium frame, a carbon fork, hydraulic disc brakes for all-weather stopping power and a simple 1x drivetrain that ditches the front derailleur for less clutter and easier operation. Don't worry, with the wide-range 11-46 cassette still gives you all the gears you need to conquer hills and crush flats. Plus, a vibration-absorbing handlebar and ergonomic grips for more comfort on every ride.
The final word
FX 3 Disc is a lightweight and fast fitness bike, commuter and neighbourhood cruiser all in one. For all the great things about this bike, the best tech upgrade is the simple-yet-capable 1x10 drivetrain.
