Features

200 Series Alpha Aluminium

Trek's high-performance road alloy, formed into sophisticated tube shapes for maximum strength and minimum weight.

Carbon fork

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

Flat Mount disc brakes

All-new Flat Mount disc brakes are more elegant, lighter, smaller and cleaner than traditional disc brakes, providing superior performance and stopping power under harsh conditions.

Tubeless Ready rims

Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for road wheels. When you go tubeless with TLR, you can run lower tyre pressure for increased traction and comfort without the threat of pinch flats.

Control Freak Cable Management

Control Freak is the lightest, quietest, most versatile cable management system. It allows any combination of shift and brake housing to be routed through the frame for clean aesthetics and an easily customisable set-up.

Hidden mudguard mounts

Discreet mounts accommodate full-coverage mudguards for added utility.

Rack mounts

Going for a long ride? Rack mounts make carrying accessories a breeze.
