AERO BRAKE LEVERS fit 3T aerobars, and other bars with standard handgrips. Sold in pairs, they fit securely over the ends of 24-mm diameter bars. They are robustly built in aluminum, with internal brake cable routing and a return spring for light action. Suitable for single- and double-pivot brakes, they take a cable with a pancake (MTB) end. At a mere 4 mm in width, these are the most aerodynamic brake levers available, and weigh just 60 g the pair.
