Light, adjustable and ergonomically perfect are just a few ways to describe Avid's Speed Dial Ultimate Brake Levers. The CNC construction and cartridge bearings make the Ultimates stiff, smooth, beautiful and durable for season after season of hard use. They work with linear-pull and mechanical-disc brakes. Plus, you can adjust the reach and the levers are made to bend not break should you crash. You can also precisely dial-in the brake feel simply by turning the Speed Dial knobs. No tools required!
