I have a TCR disc. Was using defy on NEO. No issues. noticed yesterday the flat mounted disc brake on TCR has made contact with NEO casing causing a slight indentation. I checked when I fitted and there was 3-4mm gap so can only assume sprinting has caused the 2 to come into contact. I am going to fit a spacer to increase the gap.
Bob, just loosen the caliper and move further away. Its easy to realign on bike after-even a lawyer could do it
