Avid's Elixir 9 Hydraulic Disc Brake makes you faster by slowing you down better. Avid's Taperbore technology and Power Reserve Geometry deliver superb modulation and pinpoint stops. Increased power comes courtesy of a super-stiff, 2-piece caliper that contains larger pistons and DOT 5.1 fluid for better heat dissipation and resistance to brake fade. Plus, the Elixir boasts a unique integrated reservoir and a carbon lever for major weight reduction and a sleek look, while tool-less reach and pad contact adjustment knobs let you dial in the perfect feel. The Elixir 9 even comes complete with Avid's HS1 rotor.
