I wanted more braking power so I got a 203mm rotor and adapter from ebay and it's not working - seems the rotor is too big or the adapter is too small. The rotor is rubbing on the caliper housing. The adapter packaging is labelled "180mm R", which I thought was the correct adapter for a 203mm front.
Has anyone encountered such a problem? (This isn't my first rotor upsizing - I went to a 160mm to a 180mm on this same bike without issues.)
This is the 203mm rotor/adapter that doesn't work:
