Hi

I have recently taken apart my headset for cleaning and put everything back correct.

It know feels lumpy when rotating it. I did tighten the headset bolt up very tight. Could i be applying to much pressure to the bearings ?

How tight should it be ?

Cheers

    How tight should it be ? Not so tight that its locked or as you're finding not turning smoothly, you've obviously overtightened it.

    If its an Aheadset then according to my Zinn book it should only need about 2Nm force, which is not a lot.

    I just keep slowely tightening the headset preload and then putting the front brake on and checking for play untill the play has gone then I stop tightening it.

    I check by trying to turn the spacers. If you can just do this with a firm grip it is about right.

    Initially, I tighten mine up so the steering goes slighhtly stiff - then, unscrew the allen bolt a little bit until the steering turns freely and smoothly.

    I do this first. Then do the spacer check. Sort of belt and braces.

    I removed a spacer to drop my bars and spent ages re-reading Zinn to try and figure out why I couldnt eliminate a very slight "notchy" feeling around dead centre. 20 mins of peeing around and I eventually realised it was due to the exposed cables rubbing on each other where they cross in front of the head tube :oops: .
