1x drivetrain

A 1x drivetrain means more versatility, simpler shifting and less 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.

400 Series OCLV

Ultra high performance, within reach. The areal weight range and modulus mix of 400 Series OCLV provides an exhilarating sense of acceleration and confident handling.

Shimano CUES

Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimanos new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette, and chainrings.

Upgrade your pedals and love your bike more

Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
