Gravel Specific Tyres
Wider gravel-specific tyres provide better traction and more stability while riding on gravel or dirt tracks.
IsoSpeed decoupler
The core of Trek's endurance comfort technology is our 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. It's a technological revolution.

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.
Ride Tuned seatmast
Our no-cut Ride Tuned seatmast is designed for the rigours of pro racing. It's the lightest, most comfortable solution for day-in, day-out performance and comfort, however rough the roads or hard the riding.
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.
Horizontal Sliding Dropout
The horizontal sliding dropout with redundant securing mechanisms allows for no-slip single-speed or geared options and provides the ability to dial in the geometry to match each rider’s style.
