Everybody uses these brakes, from XC racers to freeriders, their value-to-technology ratio is through the roof. Avid's Taperbore technology and Power Reserve Geometry deliver great 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 resistance to prevent brake fade. Plus, the Elixir's unique integrated reservoir provides a major weight reduction and a sleek look. It even comes complete with Avid's CleanSweep rotor.
