[Closed] Steerer tube slipping in the crown

There's nothing you can really do aside from buying a new crown assembly and getting it fitted. This is quite an expensive exercise so for a pair of Toras you'd be better off just dumping them in the skip or breaking for spares.

Shirley a perfect job for loctite?

If it really is that loose you should be able to press the steerer out (or part way out) plenty of high grade locktite and reassemble.

You are certain its not the stem turning on the steerer?

As well as the loctite you could drill it and put a nut and bolt in.

bit of chewing gum around the bottom of the steerer tube where it meets the crown and the jobs a good 'un.

Midlifecrashes - I was wondering about that but scared of weakening the crown too much.

Duct tape - surely that'll do it?

You're having a girrafe, right? 😯

Junk it.

What would be wrong with that PP? The steerer is stepped at teh bottom so cannot pull out upwards. Loctite is commonly used in this sort of application. You are not removing strength from it in any manner. The steerer is only a press / interference fit in the crown anyway.

surely if it's an [url= http://en.wikipedia.org/wiki/Interference_fit ]interference fit[/url] it will scrape off the loctite as you press it together?

are you [i]sure[/i] it's not the stem slipping?

bassspine - enough should remain on the stepped area and in any areas where the fit is slack perhaps? Worth trying to me anyway

If the Steerer's twisting in the crown you've plastically deformed the crown or steerer tube.

Applying Loctite is only going to be a short term fix - if the crowns already deformed it's going to deform further under load! Loctite is meant for bonding components together with carefully controlled tolerance's, not for sticking together effectively bent components.

Drilling and bolting the components together is even worse. Your then removing material from the fork crown when you drill it(an already highly stressed component), and effectively creating a stress riser(weak point) in the component from which micro cracks can propagate and cause structural component failure.

Persoanlly i'd put the forks in the bin ASAP otherwise you could be heading for a really nasty accident if the crown or steerer tube fracture.(i've witnessed failures of this type at a race a few years ago. Trust me you don't want it to happen to you it -it was pretty grim!)

Makes sense stom.

TJ, maybe.... although from what OP's saying

through man handling or a bad crash are basically ready for the bin now.

So fix it and then sell on?

👿

if it were me I'd be sawing the steerer off flush with the crown and then sellign them on.

is it worth the risk for a little over £100? bin or warranty them.

and TJ, stop postulating and trying to sound authoritative. I'm sure you mean well but someone might mistake your baseless opinions for fact. Its not your face that's at risk here.

wouldnt ride them my self now - thus not gonna make any suggestions on how to fix em ....

He'd already replaced them before I posted with some nice Vanillas, I was wondering if there was anything that could be done but was pretty sure they were never to be used again.

Definitely was not the stem moving, 100% it was the steerer slipping in the crown.

Not to worry. Will probably sell as spares.
