FX is our most popular bike. And what’s not to love? It has the perfect combination of road bike speed plus city bike comfort. We call it a fitness bike, but it’s so much more.


OCLV Carbon frame

Carbon is the lightest, fastest frame material, and nobody does carbon better than Trek. Our exclusive OCLV Carbon offers the absolute best ride for the money.

E2 head tube and fork

E2 tapers from a 1.5" lower to a 1-1/8" upper, placing more material where it matters most for the stiffness of a full 1.5" system without the added weight.

IsoZone handlebar and grips

Vibration-damping material absorbs road bumps and buzz for an incredibly comfortable ride.

SpeedTrap compatible

SpeedTrap seamlessly integrates the computer sensor into the fork to measure speed and distance with no added aerodynamic drag.

20 speeds

A wide gear range is perfect for the widest variety of terrain.

Crank: compact

Two front chainrings with shorter gearing, for the best combination of climbing ability and flat-terrain speed.

Puncture-resistant tyres

Tough tyres help keep punctures from slowing you down.

Oversized stem and handlebar

Oversized bar and stem increase durability and control.

Riser bar

Provides an upright ride. Easy to control, easy to enjoy.

Integrated bottom bracket

Press-fit BB improves pedalling efficiency and allows more rear tyre clearance.
