Upgrades from 7.5 FX

  • 400 Series OCLV Carbon frame with IsoSpeed

DuoTrap compatible

DuoTrap seamlessly integrates the computer sensor into the frame to measure speed, distance, and cadence with no added aerodynamic drag.

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.

Carbon fork

Lightweight fork with carbon fiber legs soaks up hand-numbing road vibration.

Blendr stem

Bontrager stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.

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.

DuoTrap S compatible

DuoTrap S seamlessly integrates a Bluetooth® sensor into the frame, so you can log your routes and track fitness progress on your computer or smart phone without an external sensor.

Integrated bottom bracket

Press-fit bottom bracket improves pedaling efficiency and allows increased rear tire clearance.

IsoSpeed decoupler

A technological revolution. IsoSpeed isolates the seat tube from the rest of the frameset, doubling compliance and comfort with zero performance drawbacks.

Internal cable routing

We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.

Puncture-resistant tires

Tough Bontrager Hard-Case tires help keep flats from slowing you down.

Rack & fender ready

Built-in mounts make it easy to add racks and fenders for added versatility.

Tubeless Ready rims

Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for the road.

IsoZone handlebar and grips

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

Vanishing fender mounts

Discreet mounts accommodate full-coverage fenders for added utility.
