Light enough for XC and powerful enough for freeriders, Avid's Elixir 5 Hydraulic Disc Brake provides world-class control and power. 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 dissipation and resistance to brake fade. Plus, the Elixir's unique design features an integrated, in-line reservoir for major weight reduction and a sleek look. It even comes complete with Avid's HS1 rotor.
