Hmm, managed to make my sprocket and lockring slip twice now in as many weeks.

I've done it up as tight as I can, even to the point of standing on chainwhip (which is now bent as a result) and lockring tools, but it's still come undone and I wasn't even skidding, I was just slowing down!

Can anyone tell me the best product for thread... gluing(?), something like thread lock?

Its only temporary, as building two new rear wheels in a couple of weeks, one with bolt on sprocket.

Tighten cog, tighten lockring, ride up a steep hill, tighten lockring....

If this doesn't sort it, you're doingitwrong.

With care....

Nah, just fucking tighten it and forget about it.

Just like with general bike mechanics, never use your body weight, tighten it up as much as you can with the strength in your arms and that will be enough.

I have a lockring that kept coming undone, I flipped it over and screwed it on with the side that had been facing out now facing in and it hasn't budged since. I guess the start of the thread was damaged on one side or something?

I used both my max arm strength and holding the whip with foot on it and turning the wheel itself by hand, and I ain't weak or light, I tightened as far as I could and at that point even thought the threads might be going, but it still came undone.

Don't have any hills steep enough or long enough round my way!

Never come across this before, will give it a go, cautiously!

^^ Tried that already Shinkuu.

Cheers guys, will try and if it don't work perfectly, its not the end of the world, new wheels, sprockets and securing methods coming soon anyway.

Sound like your lockring may not be deep enough to put enough purchase on the cog.

decided to keep my old frame due to non payer on ebay

^^ That actually might well be the case Ed.

It is a crappy one that came free with the wheel and is very thin.

Cheers.

^^Fair, never seen one in the UK, only in pics and vids from the US. Looks pretty good, but needs tape. ;)

I had that kinda problem with a condor lockring, was fine for a while but came undone on a skid stop. Switched back to the much beefier one that came on my nova-techs and it's been fine since

I believe Goldtecs use a shimano threading lock ring, any out there that are particularly fat and solid, preferably in black? Was thinking of going for a DA ring, but if there's anything better, would appreciate the advice.

AngelD just to check you are tightening the cog, then the lockring. Riding (with no backward pressure) then re-tightening the lockring (fking hard this time)?

This is how I've always done it. I have weak arms but ok legs!

:P

Profile make a chunky one. The width is only going to help the tool stay on though (and a better spanner would sort that), It won't be inherently more secure because it's fatter.

H+ rims are shit, well at least they look/weight it.

I wouldn't go any deeper that a velocity, make sure you get ones without a silver brake surface though.

Lol. Some good InternetFacts there DFP.

Miro_o - I did put on the sprocket tighten till I thought I was gonna strip the threads, then do same on lockring, but didn't retighten after a ride, will keep that in mind.

Also, a thicker lockring will have more surface area on the threads, therefore offering more grip and purchase and so less likely to come loose... I think!

Will check out profile, cheers guys.

Once ridden the chain can tighten the cog down a bit. You need to tighten the lockring again once that's happened.

I'm pretty sure lockring threads cover all of the thread on the hub.

Yeah, that really should have occurred to me before about retightening after quick right!

Thats also the problem with my current lockring, its only about 2-2.5mm wide and really isn't covering all the threads! In fact, its so thin, its actually flared out from the center as I've tightened it!

Crappy phone pic to illustrate -

This is the wrong kind of vice for a bike workshop. Serrated jaws will chew up tools.

its sad that at that age you still feel you need to prove your point on the internet so badly:)

If you say something condescending and sign it off with a smilie face that doesn't make it less condescending, it make you an utter tosspiece.

^ Now that made me laugh!! And kinda agree...
