Posted this before but been on holidays and no joy with suggested solutions. Under braking, especially heavy but not really anything dramatic the spokes start to clang on the brake calliper.
Only happens under braking and therefore can't view what's moving where by pushing and pulling anywhere on the bike.
Definitely appears to be related to braking force.
Last time I asked the question everyone was firmly of the opinion it was the brake mounts being loose. I've looked today though and there's no play at all and all looks solid.
Any thoughts as to what it could be please? I'm at a real loss but I'm none too happy about spokes hitting brakes….
