Is the Trek FX 3 Disc good for commuting?

Yes. It has rack and fender mounts, hydraulic disc brakes and puncture-resistant tires, which cover most daily commuting needs. The upright flat-bar position keeps you visible in traffic.

How does it compare with the FX 2 Disc?

The FX 3 steps up to a carbon fork, a 1x drivetrain and lighter components. The FX 2 uses an alloy fork and a 2x drivetrain, so it costs less but rides heavier and shifts with more gear choices.

Can it handle gravel roads?

Light gravel and packed dirt paths are fine, but the 32 mm tires and rigid frame are not built for loose or rocky terrain. For real gravel, a bike with wider tires and more clearance suits better.

What is the weight of the Trek FX 3 Disc?

Trek lists about 25 lbs for a medium frame. That is typical for an aluminum hybrid with a carbon fork, and lighter than most budget hybrids.

Does it come with rack and fenders?

No. The frame has mounts for both, but racks and fenders are sold separately. Budget for them if you plan to commute with gear or in wet weather.

What sizes does it come in?

Trek offers the FX 3 Disc in a range of adult frame sizes from small to extra large. Check Trek's size chart by height and inseam, since the flat bar and frame geometry affect fit.
