Headset top-cap is pulling through the stem, advice please..Spunout

New problem re-building the front end.

My Cane Creek S2 top-cap is pulling through my Thomson stem. Meaning, as I tighten it up, it just falls down the stem until it rests in contact with the top of the steer tube! WTF??

Anyone heard of this happening? I'll call the LBS first thing to look for a new top-cap (maybe a fancy record carbon one) but this is bizarre!

You old guys, I once said that a threaded headset was install and forget; unlike threadless. I re-iterate that statement.
Do I need to hit play on my tape recorder!the bull

Get the king! Trust me!
Make sure the steer-tube is about 3mm below the top of stem!
Do you have a shim on your steerer?
Not sure exactly if this applies to your situationFez

but I heard the Cane Creek topcaps are designed to deform if you accidently overtighten them, saving you damage on other parts.

I have the same headset, but I don't use the S2 topcap because the steerer is carbon.
1" top-cap in a 1" 1/8 stem? nmBruno S

No shims, all 1 1/8" setup. Deforming could be it...Spunout

I cranked the top cap a bit to make sure the bearings were all well seated, then backed it off and re-set the preload.


A quick fix would probably to get a very small spacer to put in there, that would stay above the stem but under the cap.

Bull, how many Chorus headsets can I get for the price of a King?

Measure the diameter of the top cap. It must be larger than 1-1/8". If it's not, get an appropriately sized top cap.
