Designed with direct feedback from Trek-Segafredo team racers to help make the fastest bikes and riders in the world even faster.

Simple, smart cable management design makes routing easy, keeps your cockpit clean and your cables out of the wind.

The integrated bar-and-stem combo delivers a lighter, faster design that can add free speed to any ride.

It's nearly 10% faster than its predecessor and saves riders seven watts of effort based on wind tunnel testing calculations.

Our proprietary OCLV Carbon construction delivers a bar/stem that's ultra-light, compliant and durable.

Blendr makes it easy to cleanly integrate your light and Garmin. A Blendr Mono and Duo base and mounts for Ion lights and Garmin computers are included.

The Variable Radius Compact (VR-C) bar shape allows a longer reach (100 mm) and drop (124 mm) that creates the ideal hand position for quick transitions from the tops to the drops.

If for any reason you’re not satisfied with a Bontrager or Trek aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.
