Overview

It's right for you if...

You're ready to log big miles, and you prefer the feel of a flat handlebar to the drop bars that come stock on most road bikes. You prioritize comfort and performance equally, and want the simplicity a 1x drivetrain provides.

The tech you get

A lightweight OCLV Carbon frame with a road-smoothing IsoSpeed decoupler, a Shimano GRX 1x11 drivetrain with a wide-range cassette, Shimano hydraulic disc brakes for all-weather stopping power, a lightweight tubeless ready wheelset, and ergonomic grips. Plus, it's easy to accessorize with fenders, lights, and more!

The final word

Fast, capable, comfortable. This bike has a road -smoothing carbon frame and quality parts that will hold up over serious miles, but what really sets this model apart is the simpler shifting experience the 1x11 drivetrain provides.

The Walkthrough
