Hi,

A quick one I hope. I've recently swapped the stem on my Bianchi 928 C2C and whilst everything appears to be tightened up correctly and I can't detect any play in the headset, a small gap appears to have opened up at the fork crown. See here

It is looking a little gritty - since cleaned - but I'm sure the gap at the fork crown is larger than it was previously:

Doesn't seem to be any movement there though. Am I worrying about nothing?

Cheers,
Steve

    Nobody got any opinions on this? :shock:

    Had a quick look in the LBS on the way to the train - on the new (very nice!) C2C Infinito the fork crown looks to be pretty much flush with the underside of the headtube.

    Cheers,

    Undo the headset cap and stem bolts.

    Press down so all the gaps are closed. Tighten the headset cap bolt. Then do the stem up...

    I have tried that - loosening headset cap and stem bolts and leaning heavily on the top tube right behind the head tube didn't appear to close them up.

    I shall give it another try tho.

    I guess that tightening the headset cap doesn't preload the bearings in the same way it does with a star fangled nut?

    I took a closer look today at it seems like, having looked at the assembly on the Park Tool website, it is actually the fork sleeve that's sitting a little high.

    I haven't cleaned it all out and re-greased it all, but it looks like the fork sleeve is siting flush against the bottom of the lower bearings in the head tube. The grease there still appears white, so doesn't look like any cr*p has got in.

    Any suggestions? I'd like to try and learn how all this fits together correctly myself.

    Thanks,
    Steve
