Re: Weird Behavior - Vex Pro Ball Shifters

another thing to remember is the radius of the spool you are using to wrap a strap around if that is your way of pulling. We over looked the diameter of the spool and use a 2 inch diameter spool. If it is 1 inch diameter than you are halfing the torque put on the balls allowing more force for releasing and using the cylinder set up.
