IsoSpeed decoupler
At the core of Trek's endurance comfort technology is the IsoSpeed decoupler, the result of an 18-month study of how a racing bike performs over rough roads, and how that performance affects the rider.

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.
12mm Thru-Axle
A 12mm front thru axle makes steering more precise for more control, and the quick-release feature makes wheel removal easy.
Carbon Armor
Sometimes you need a little extra protection, so we developed our light, tough external Carbon Armor polymer shield. It provides reassurance when you know your down tube is bound to take some abuse.
Control Freak Cable Management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout, and dropper post lines to be routed through the frame for clean looks and the ultimate custom setup.
Horizontal Sliding Dropout
Horizontal sliding dropout with redundant securing mechanisms allows for no-slip singlespeed or geared options and provides the ability to dial in the geometry to match each rider’s style.

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

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
