The eeBrake G4 is the fourth generation of the legendary eeBrake featuring 100% CNC machined parts a wider design optimized for 22 � 28mm rims stiffer black arch spring a revised one-piece center adjuster with built in resistance for easier use. The all-new titanium eeBrake cable adjuster pivots as the brake is applied optimizing cable alignment during brake actuation and reducing friction for greater power. Cross Cable Path aligns the brake cable over the center of the brake this alignment provides a graceful clean line and moves cables into the `wind shadow` of the frame providing an aerodynamic advantage. The tool-less adjustability provides super precision and pad motion consistency through the patented �Link� pad travel proportioning system. Optimized to work with Shimano Campagnolo and SRAM levers
