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 Alpha Gold Aluminum frame, a carbon fork, Shimano flat-mount hydraulic disc brakes for all-weather stopping power, a wide-range 18-speed Shimano drivetrain that's great for conquering hills, a Bontrager Satellite Plus IsoZone handlebar and ergonomic grips, extra mounts for accessories like a rack and fenders, and puncture-resistant Bontrager H2 Hard-Case Lite tires.
The final word
FX 3 Disc is a lightweight and fast fitness bike, commuter, and neighborhood cruiser all in one. For all the great things about this bike, the best tech upgrade is the 2x9 drivetrain. This 18-speed setup is like what you'd see on a road bike: light, efficient, and built for speed.
