I bought some DT SWISS XRC forks earlier this year. They have a carbon steerer and are married to a Chris King headset.
The problem i am having is that although i ensure my DT Swiss expanding steerer Adaptor (star nut) thingy si done up to at least 8Nm as specified, as soon as i try and tighten the headset, the top cap bolt pulls the 'star nut' out. I imagine this has something to do with the tightness of the top race of the King headset, but i guess there may also be something wrong with the 'star nut'. I don't really want to tighten it beyond 10Nm as it is a carbon steerer.
Anyone have any experience? I'm guessing DT may do a warranty replacement. Maybe there are other such expanding nuts on the market? Or, maybe a standard starnut is fine...?
Thanks in advance
