Hello,

I don't have another Brompton to use as a reference.

A couple of weeks ago, I had a Brompton-endorsed LBS replace the headset on the Brompton I bought years ago: The mechanic found the wheel didn't turn smoothly, and he suggested getting a new headset.

I just noticed that when applying the front brake and pushing forward, there's a bit of play between the nut and the lock nut. I don't have a 36mm skinny spanner, so could only use an adjustable spanner to check that the lock nut is tight.

Is that play normal, or should be there no play at all?

Thank you.
