Here is a little insight in KHE´s lab. One of the last products we are working on includes a new way of adjusting the gap of your freecoaster and a dual F-Set rotor! Freecoaster with hydro-slack adjustment: Based on a hydraulic system, we managed to create a freecoaster that can be adjusted directly by the means of a shifter. The hydro-slack adjustment shifter can be placed on the handlebar and allows for an instantaneous slack adjustment (patent pending). No more tools needed, no more time wasted! Dual F-Set rotor: Because many riders still like to ride with brakes, we developed a new dual F-Set system that allows running our new freecoaster with hydro-slack adjustment without having any cable in the way.
As you can see on the technical drawing, you have two internal rotor system in one: on top is the F-Set (for rear brake with classic cable pull) and at the bottom is our new patented internal hydro-rotor (hydraulic system).
Of course, the picture shows our very first prototype of the hydro-slack adjustment freecoaster. Many things may change before going into production, but so far, everything runs smoothly.
