No its not my shrunken brain wobbling around in my skull.
On the tandem when going over bumps there is a clunk that is felt rather than heard. I cannot locate it to one area. It feels almost like “topping out” of the fork but the fork has a soft stop for top out and runs a lot of sag anyway
Headset has no play, axles have no play. I can’t find anything loose. Its not harsh like metal on metal anyway.
The fork legs have a small amount of play in the bushes but I can’t see how this would be it as it happens even on fairly small bumps where I doubt the load comes of the fork altogether.
It doesn’t feel nasty and destructive like a hard impact metal on metal but its bugging me
Any thoughts apart from ignore it?
