Just purcahsed a centrelock wheelset and centre lock adapter from on-one but can't figure out how the adapter works. I've fitted the rotor to the adapter, placed it on hub, but the centrelock disc used to tighted up the whole arrangement hits the rotor heads. There was another screw type cap that came with the adapter but the OD of this is the same as the OD of the hub centrelock so doesnt work. Can anyone shed any light on whats wrong, have on-one simply sent the wrong centrlock adapter cap ?
thanks for help.
Adapter is here
