I heard from Don Grubee that he will have a new design CC coming in about a month. It can retrofit the old design. New design rotor pads will have tread grooves and have a metalic base to grab bell drum better and not slip designed to run in an oil bath which will be much better for the gears to get constant lube with no clutch slip. So be sure to nag Bicycle-Engines.com so he gets some in when there available.
