The S-990 aero brake lever is more than just a lightweight, aerodynamic, and powerful carbon aero brake lever. What makes it truly outstanding is its built-in adjustment feature. A simple turn of a 2mm Allen key frees the lever to spin, allowing the user to make up to 8mm of inward or outward adjustment to their brake calipers. Such wide adjustability makes it easy to fine-tune hard to reach brakes on the most innovative aero triathlon and time trial machines, which feature integrated aero brake systems that require time and tools to access.
