Applied technologies

In this chapter, we explain the technologies that the manufacturer uses for this product.

Porter and Fender Compatibility
The integrated eyelets facilitate the mounting of racks and mudguards for an extra portion of everyday life.

DuoTrap S compatible
DuoTrap S integrates a Bluetooth® / ANT + sensor into the frame. Capture your tours and fitness progress on your computer or smartphone without an external sensor. The sensor is compatible with all other devices that also use ANT + wireless technology, whether Bontrager, Garmin, PowerTap or SRM.

Blind frame stem
With Bontrager stem technology, you can attach your equipment directly to the stem for a clean look and maximum ease of use.

Puncture-proof tires
Robust Bontrager hard-case tires - so you do not have any problems.

Alpha Gold Aluminum
Trek's lightweight, high-performance aluminum is cold-extruded and butted in an extrusion process and then placed in complex pipe profiles for a good balance between strength and lightweight construction.

Carbon fork
The lightweight fork with carbon fork blades absorbs the tiring vibrations of the road.

IsoZone handlebars and handles
Suspension for your hands. Trek's exclusive IsoZone vibration-damping material absorbs road bumps for better control and an incredibly comfortable ride.

Tubeless ready rims
Bontrager TLR Road is the first fully integrated tubeless system for the road. Without a tube, breakdowns are a thing of the past and you can drive with less tire pressure. Lower tire pressure means more traction and control. And the greater comfort reduces the fatigue. But the best part is: The tire sealant seals punctures immediately when they happen.
