I used to be bordered with chatter, but not anymore.
What was the solution for me was a good headset that doesn't loosen up all the time.
It seems to me that a standard 36/45º alu cup design like Ritchey and Cane Creek just don’t do it.
If you're able to mount a fork mounted cable stop like Darkmother's mention, I think that's a very good idea too.
If the headset loosens, when if it's a Ritchey, Cane Creek or any other standard 45º cartridge type,
the fork wobbeling wont interfere with the brake pads pressure to the rim.
