Steerer Tube Star Nut Problem

edited April 2010 in MTB workshop & tech
Took my headset apart for a clean yesterday. Once putting back together I noticed the srat nut in the top of the steerer tube had become corroded after this winters riding. I screwed the top cap into it and the thread in the star nut has come away from on side. It still holds the bolt tight. obvoiusly I need to replace it bit would it be Ok to ride still as I have a new headset coming this month.

    Well headsets don't normally come with new star nuts so you would have to buy one anyway (unless your new states it is)..and for the sake of a couple of £s.

    all it does is allows the headset to be preloaded.

    once the stem has been tightened you could just remove the top cap and ride the bike.

    So if you can set the headset. you will be fine.

    nicklouse, that was my thinking. It will wait a week until I service it then.

    Just about to order my new Hope Headset and noticed this thing called a Hope Hed Doctor which replaces your star nut. Also looks like it will make the top of the steerer tube more water tight, therefore less corrosion

    The Hed Doctor is a great piece of kit. It can be removed if you're swapping the forks and IMO is a much better solution than hammering a star nut into your expensive steerer. The bolt is stupid light and can be stripped without too much difficulty* but as said above it's only used to preload the headset, it's not like its holding the forks in place.

    * so I'm told

    I agree with .Blitz, but we're in a pretty significant minority I think.....

    when you say corrosion; is the starnut or the steerer corroded .... is it an alu steerer?

    Beer in moderation ... is a waste of beer

    If riding an XC race bike is like touching the trail,
    then riding a rigid singlespeed is like licking it
    ... or being punched by it, depending on the day

    I have seen Hed Doctors welded to steerers - be careful.

    Star nut everytime for me.

    Different materials, dry welding.

    Yeah it was the star nut, plenty of wet sand had got onto it and done the damage, steerer fine. Hopefully I wont end up with the hed doctor welded into my nice Fox Forks, ordered now.
