Hi Raphi , The carbon wheels must be very nice. I hope that is not the only way to resolve the damper issue with the aluminum rim hubs. It seems very reasonable to replace the dampers when new chain and sprockets are required. But every 3000 to 4000 miles is too much especially with normal use. A good chain and sprockets with regular maintenance should last 15,000 to 20,000 miles. Have you had any relief from the factory about this ?
