Light enough for XC and powerful enough for freeriders, Avid's Elixir R provides world-class control and power. Avid's Taperbore technology and improved lever pivot location 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. This fine brake also uses a tool-free reach adjustment that allows you to balance your levers for superb bar feel. Plus, the Elixir's unique design eliminates the need for an independent reservoir for major weight reduction and a sleek look. It even comes complete with Avid's Clean Sweep rotor.
