A 1x drivetrain means more versatility, simpler shifting and fewer things to go wrong. You still have a wide range of gears, but with lighter and more intuitive shifting. Everything you need and nothing more.

Just-right geometry
The all-new FX Sport has slightly less reach and slightly more stack than previous models for a more comfortable yet active and fast riding position.
