A 1x11 drivetrain means more versatility, simpler shifting and less things to go wrong. You still have a wide range of gears, but with lighter and more intuitive shifting. Everything you need and nothing more.

Ultra high performance, within reach. The areal weight range and modulus mix of 400 Series OCLV provides an exhilarating sense of acceleration and confident handling.

Hydraulic disc brakes offer the absolute strongest stopping power in all conditions, including wet and muddy.

Our innovative decoupler allows the seat tube to rotate independently from the top-tube-to-seatstay junction, increasing vertical compliance without compromising pedaling efficiency.

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

DuoTrap S (sold separately) integrates a Bluetooth®/ANT+ sensor into the frame. Log routes and track fitness progress on your computer or smart phone with no external sensor. Works with all major ANT+ wireless players, including Bontrager, Garmin, PowerTap, and SRM.

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

Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for the road. No tubes mean there’s no pinch flats, allowing you to run lower tire pressure. With lower tire pressure you can increase traction, control. and comfort, reduce fatigue on you. Best of all, the tire sealant seals up punctures as soon as they happen!

Suspension for your hands. Our exclusive vibration-damping IsoZone material absorbs road bumps and buzz, giving you more control and an incredibly comfortable ride.

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