I've always wondered about these. Not having any off road experience I was not familiar with the concept. I'm having a hard time envisioning how these can help keep the pedal from being pushed inward. Clearly there has to be enough slack in the cable to allow the pedal to travel up and down so how does it help otherwise? Seems a guy could buy some coated cable and fittings at Home Depot and build one for a few bucks.
