500 Series OCLV

500 Series OCLV achieves a superb balance of light weight, strength, and stiffness that's perfectly suited to the sophisticated frame technologies that distinguish Trek frames.

E2 head tube and fork

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

Crown-mounted housing stop

Isolates the brake cable from steerer tube flex, significantly reducing chatter for better braking performance in all conditions.

Gary Fisher Collection

Innovative bikes imagined by Gary Fisher, built by Trek.

Adjustable cable routing

Allows you to run portions of the internal cable routing with or without full housing.

BB90

BB90 is the widest bottom bracket available on a road bike. This Trek-exclusive carbon BB makes the frame lighter, stiffer, and quicker to accelerate.

10 speed

The standard in race performance gearing.

Internal cable routing

Shift and brake cables are routed through the frame for the lightest, cleanest, best cable management ever.

Direct-mount front derailleur

Provides accurate shifting in a lightweight, minimal package.

Crank: cross

Cyclocross-specific 38-46 gearing.

Anatomic-C handlebar

Next-level ergonomics feature flared drop bars with a short reach for better leverage and smoother, safer hand transitions.

Vanishing fender mounts

Frame is fashioned with discreet fender mounts so you can ride all year long.
