"For road hub conversion please refer to
this web page. No Shimano road discs can be converted as the dish changes – you will have to buy a new disc to run Shimano 11 speed. For older discs, you can run Campy 11 speed by adding a second 0.25mm washer between the drive side bearing and the Campy free hub."
