Build a clean, fast front end with this dedicated headset kit for fitting LEVEL 5 or ULTRA-AERO integrated carbon handlebars to Ribble ULTRA-AERO SL R and SL carbon frames.

Designed to work seamlessly with Ribble’s fully integrated aero cockpit, this kit keeps steering smooth and predictable while allowing hoses and cables to run neatly through the bars and frame. The result is a front end that looks sharp, feels stable at speed, and stays quiet mile after mile.

Matched bearings deliver consistent, confident steering, while the included compression spiders and stackers help you fine-tune bar height and fit. Whether you’re building a new frame or refreshing an existing setup, this kit keeps everything aligned, secure, and ready to ride hard.
