Loose headset problem(9 posts)

Loose headset problemJohnIV
Jun 3, 2003 5:50 AM
Does anyone know where I can get an aluminum compression plug for a carbon steerer fork. I can't get the Reynolds compression device tight enough to eliminate slopiness in the headset. FWIW, it's an integrated headset, which I am starting to hate. Anyway, before I give up and buy a new frame/fork, I want to know where I can get one of those compression plugs that you glue in. Can anyone help? Thanks.

Exactly what brand of headset? I had a similar problem with a Campy Hiddenset.

mja - were you able to solve the problem with your Campy HS? I have the 1" Hiddenset on my 'cross bike and can't seem to eliminate the play in it. If there's a fix that you (or anyone else) can pass along I'd appreciate it.

I wish I had a specific fix: The headset finally tightened up on what was at least the third attempt -- after completely disassembling the entire fork/headset assembly repeatedly. On the successful attempt I made a point to grease every surface that slipped, or was slipped against, with a light film of grease. I also intentionally over-torqued the [Reynolds] expander-plug cap, released, and then re-torqued to a more appropriate setting, to ensure that the races were pulled up into the headtube sufficiently. (After first determining, with a torque wrench, exactly how much torque the expander plug could take before slipping.) One other step I took was stacking up spacers over upper-bearing cone race (white plastic piece), so that I could use a mallet to tap the cone race into position, instead of just pressing it in by hand. So, I don't think I like integrated headsets!

I'm not familiar with the Reynolds plug, but if it is all metal (no rubber), I would think that it could be glued in with epoxy.

You could also try another brand of plug. Supergo sells a plug that is similar to the one sold with Mizuno forks. There is no guarantee of a proper fit however, since there is no standard for the I.D. of a 1-1/8" carbon fork.

I would also be sure that you have the correct headset for your frame. What brand of frame and headet? Someone recently posted that they were trying to use a campy hiddenset with a Litespeed frame. Litespeeds must use the Cane Creek headset.

It doesn't sound right that you should need a lot of top cap pressure to eliminate slopiness. The bearing seats are either 45 or 36 degrees and automatically center in the angled seat when the top cap is tightened. If the headset is tight initially, but loosens after riding, you may have a problem with the stem loosening on the carbon steerer.

Something is not right. Theoretically you do not need the plug. It is only there to make it easy to take the play out. You could accomplish the same thing without it. Sounds like your fork is too long(have you checked?) or something is not seated correctly. Has this been an ongoing problem or has it srfaced after many miles?
good point about steerer length...C-40

I always assume that folks know the basics, like the fact that there must be some clearance space between the top cap and the steering tube either by cutting the steerer 1-3mm shorter than the top of the stem, or by installing enough spacer on top of the stem to provide the clearance.

After two years of flawless performance and one major overhaul, my bombproof 1" Campy Chorus headset has come undone this week. No matter how far down the steerer tube I initially seat the expander nut, I can't seem to eliminate the play when torquing up the bolt. The bolt seems to bottom out. I have both sets of cups/cartridge/races snugged, but the setup is still loose. Should I replace the expander bolt/nut? I'm using the original Look bolt/nut unit. Any help would be appreciated.
FSA Compressor Pluggav

I used a FSA compressor plug for mine and it worked quite well.. I couldn't get it to work at first, but the LBS that I went to for the emergency fix found out that there were two adjustments on it. One to pull the top cap down and the other to expand the plug.. The first one acts similarly to tightening the top cap to on the star nut. But anyways, once he discovered the second adjustment, it worked great! Hope that helps..
