The FX S 4 was built for speed and performance. Even in the rain!

The FX S 4 is what happens when you let the designers and engineers out of their cubicles. You can tell just by looking at it. That sleek hydroformed aluminum frame and carbon fiber fork says "I'm ready for a workout". Trek's exclusive 200 Series Alpha aluminum frame has been shaped for light weight and high performance. A tapered steerer tube and carbon fiber fork add handling precision to every corner and bend. Internal cable routing and an aperture in the left chainstay for a DuoTrap S speed/cadence sensor (sold separately) helps keep that sleek look wherever you look. Rack and fender mounts let you accessorize to your heart's content. Even the alloy Bontrager stem comes with a convenient light or computer Blendr mount.

Shimano's 10-speed Tiagra shifters feel precise and lightning-fast under your fingertips, while Shimano derailleurs add long service life and smooth operation. A 48/34T Shimano crankset and 11-34T Shimano cassette boast a huge gearing range for tackling steep inclines and speedy descents. Helping to keep speed under control is the job of Shimano's hydraulic disc brakes. That's right, hydraulic. Just like on a car or motorcycle! The stopping power and lever feedback ensures safer stopping in wet or dry conditions. Bontrager supplies the 32-spoke tubeless-ready alloy wheels and 700x32c R1 hard-Case Lite tires for easy acceleration and a smooth feel. Bontrager's H1 saddle sits atop an alloy Bontrager seatpost, while a Satellite Plus IsoZone handlebar and long-tail handgrip takes the edge off road vibration.
