The built-in adjustability of SRAM’s 990 Aero Brake Levers makes it easy to achieve your preferred braking feel on almost any aerobar setup. A turn of a 2mm Allen key frees the lever to spin, allowing the user to make up to 8mms 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 triathlon and time trial machines.
