Hi all, don't want to start a long discussion as headset problems have been more than covered, however I finally gave up with google and am hoping someone here can help. In short I have purchased a second hand specialized allez e5 sport - all good but headset has play. Did all correct tightening etc. Bearings are correct but the top race/compression ring wont tighten around steerer (not even close) It's really loose going on which seems odd (see pic) but is the correct size (30mm inside diameter) The steerer is untapered (original one that was purchased new) and is still correct diameter of 28.6mm. As there are no smaller top races than the 30mm which appears to be the correct size what am I missing here???? At present I have a rubber o ring wedged between the top race and the steerer - not ideal but is better than without. Then only way I can get the top cup to not have play in it (without the o ring) is so tight it's silly. Help, am at a loss.
