It's right for you if...
You're a commuter or fitness rider who refuses to let a little foul weather ruin your time in the saddle. You're looking for a versatile, comfortable bike with quality parts that will perform on longer rides—even when you stray from the pavement to rougher surfaces like rail trails.
The tech you get
A lightweight Alpha Gold Aluminum frame and FX carbon fork, Shimano hydraulic disc brakes for all-weather stopping power, a Shimano Acera/Alivio drivetrain with 27 speeds and a wide range of gears for hills, a Bontrager Satellite Plus IsoZone handlebar and ergonomic grips for comfort on long rides and uneven terrain, 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 commuter if you want it to be, a fitness bike when you feel like working out, and a cruiser when you're riding the neighborhood with your family. What really makes this model stand out are the upgraded hydraulic disc brakes, which are smoother than mechanical disc brakes and deliver incredible stopping power in muddy and rainy conditions.
