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 and ghosted laser etching that will stand the test of time - all with the same extraordinary stopping power and light weight that you've come to rely on from eeBrakes.The eeBrake titanium cable adjuster pivots as the brake is applied optimizing cable alignment during brake actuationThe cross cable path aligns the brake cable over the center of the brake which provides a clean and aerodynamic line moving the cables into the "wind shadow" of the frameCable housing extends to lower tip of the cable adjustment screw eliminating added friction to provide even and friction-free braking powerTool-free caliper centering adjustability provides super-precision and pad motion consistencyOne simple flip of the lever on the Quick Strut release opens wide enough to easily clear a 31mm tire allowing for easy wheel removalOptimized to work with Shimano Campagnolo and SRAM leversHand-built in Fletcher NC
