The FX 4 Disc does lots of things well. If you need a bike for plenty of different rides, this might be your dream bike.

The bicycle industry used to hang its hat on only making bicycles lighter. The FX 4 Disc demonstrates that Trek makes bicycles lighter and better. The FX 4 Disc's frame and fork get the bike nice and light pretty easily. A shaped and hydroformed aluminum frame made with Trek's exclusive Alpha Gold series aluminum provides a light and strong platform for the FX 4 Disc. The bike's FX carbon fiber fork is light, strong and even soaks up fatiguing vibration better than any alloy fork. Rack and fender mounts add versatility, while internal cable routing keep the FX 4 looking sleek. Want to keep track of your rides with a smartphone app? There's an aperture in the left chainstay for a DuoTrap S speed/cadence sensor (sold separately) that will communicate with it. Cool, huh? From commutes to day trips to rides to the grocery store, the FX 4 is more than ready.

Need your dream bike to be as tough as it is light? Shimano supplies an 11-speed Deore mountain bike shifter and clutch-equipped Deore off-road rear derailleur for lightning quick gear changes, even on rough surfaces. The 11-51T Shimano Deore cassette and 42T single ring crankset bring a huge gearing range to the FX 4. Bontrager's Affinity Disc wheels are tubeless-ready, and they're wrapped with 700x32c treaded Bontrager H2 Comp tires for a smooth feel and confident grip. Shimano hydraulic disc brakes deliver excellent stopping power in all conditions, rain or shine. A comfy Bontrager H1 saddle is an excellent perch for hours of riding. Bontrager's Satellite Plus IsoZone handlebar and grips soak up fatiguing vibration, making every mile easier.
