The hybrid world has seen some "extreme" machines in recent years: Practical, but very heavy. Lightweight, but impractical. Fast, but not very affordable. Would there ever be a bike that could do everything well? And fit better to boot?

The FX S 4 for women is here to answer that question. After a redesign of their 2017 frames, Trek discovered that adding disc brakes to the FX S 4 could improve overall control without raising the price or tip the scales in the wrong direction. The FX S 4 WSD also adds a better fit for a wider range of riders and rider flexibilties. Need a short standover height? The FX S 4 Women's 14" frame can accommodate a 23" inseam!

But back to the design. The FX S 4 starts wih a 200 Series Alpha aluminum frame and carbon fiber fork, keeping weight low while improving ride quality and torsional strength. Internal cable routing adds a clean look, while rack and fender mounts make the FX S 4 a great commuting machine. There's even a mount for a Bluetooth/ANT+ speed and cadence sensor (sold separately) in the left chainstay.

Shimano's 10-speed Tiagra shifters offer fingertip operation (with metal thumb levers instead of plastic) of the Shimano derailleurs, boasting lightning-quick gear changes and long service life. The 50/34T Shimano crankset and 11-34T Shimano Tiagra rear cassette keeps a huge gearing range for steep climbs and trips to the grocery store. 32-spoke Alloy Bontrager wheels give the FX S 4 a smooth feel and easy acceleration, and are tubeless-ready. Bontrager supplies the 700x32c AW1 Hard-Case Lite tires for needed reliability on commutes to and from work and workouts. Reigning in speed is the job of Tektro's hydraulic disc brakes, ensuring positive lever feel and wet weather reliability. Bontrager also brings a women's H1 saddle and alloy SSR seatpost to the party. Up front, the Bontrager Satellite Plus IsoZone handlebar and grips adds even more comfort over rough and choppy pavement, while an accessory-ready alloy Blendr stem has a mount for a computer or headlight.

When all is said and done, the FX S 4 WSD makes a stong arguement for a one-bike garage!
