So are all centerlock adaptors compatible?? I am building up some xtr hubs to use with Marta SLs and I am trying to figure out what rotors to use. The new Storm SL's seem to be a good choice but I would need an adaptor and I was wondering if I need an actual Magura or if any of the generic adaptors will work. My other option would be the Ventidiscs which I have heard good things about but they are a good bit heavier. Any ideas?????
