Headset loose?(3 posts)

Headset loose?slasher

When my stem is off the fork steerer, there is a definite knocking sound when I rock the bike back and forwards with the front brake on, and the fork steerer seems to move in the top headset cup 2 - 3 mm. With the stem on nice and tight it doesn't happen, but I would have thought the headset shouldn't depend on downward pressure from the stem to prevent movement. Am I correct and my headset is loose, or is this how it's supposed to be?

...then no, your headset is not loose. If you had the same knocking sound happening when your stem was on your fork steerer tube, then your headset would be loose. The stem is what keeps everything tight, once the slack has been taken out by the top-cap. I have a Chris King 1 1/8th headset and a Reynolds Ouzo Pro fork and, without the stem on the fork steerer, I get roughly the same amount of play as you indicate.
Yes the stem has to be on to keep it tightspookyload

The top cap screw provides preload on the bearings,and the stem tight on the steerer is what keeps it in place.
