WCS 4-Axis 73D Stem



Inspired by the diversity of the riding around his home in northern California, Tom Ritchey designed the game-changing 4-Axis stem to perform wherever he rode – long tarmac stretches, savory singletrack, and never-ending gravel roads. We also know more than a few people who mount the 4-Axis on their cyclocross bikes.

With its unique faceplate design, the Ritchey WCS 4-Axis carefully and confidently holds bars and offers confidence and control no matter the surface. And the 4-Axis can be flipped to offer 17° of positive or negative rise, allowing you to easily dial-in your fit for a pronounced upright posture or an aggressive attacking position.
