Need a new lockring

I've had the locking for about a 6 months and I noticed today (whilst fixing a puncture) that the locking has cracked right the way through is this:
A) Poor lockring?
B) Damage caused by fitting the lockring with a hammer and screwdriver?
C) Some other mystical force?

I am worried that B has caused the problem so I presume it would be a prudent move to my a locking spanner?
Anybody go any ideas on what caused it?

Examine the fracture surface. Are there any bubbles or defects? Unlikely I suspect. I would suggest number 2 might not have helped but lots on here use that method.

(b) use the right tool for the job

They are so thin those lockrings, and the notches are so shallow that getting it tight is a fine balance of doing it up before it strips the thing out.

I got rid of mine and just use some cheapy thicker one now, not had to touch it since putting it on.

do you skid a lot?

Fairly often, do you think the extra pressure of skiding could have done it?

i think that is more likely to have done it than hammering it on.

no way, it has to be the hammer.

hammer and screwdriver??

Using B, you're 'attacking' the lockring rather than 'prying' it with a lockring tools, you were pretty much cutting it in half.

B.

You murdered the poor thing. It was trying to help you and you killed it. (sniff).

A cheapy hinged lockring spanner does the job for me. They don't have to be mega-tight.

I did search, but...

It seems Miche aren't the only manufacturer that make their lockrings from soft cheese... Finally getting the polo bike sorted so go to take the lockring off (in the correct direction, clockwise, before anyone gets smart) and my Shimano tool takes the notch with it... I spin it 'round and try again, being much more careful this time and skraaaang! Same thing happens... There are three notches on this lockring, I don't need to tell you what happened to the third one...

Anyway, there is now no way of taking this stupid fucking lockring off with the Shimano tool... What's my next move? Mole grips?

Stupid, fucking polo bike... And Jebus, Marathon Pluses are tough to get on... I've now lost all the feeling in my hands... ;o

bench vice

Or a bench vice. But you have to be careful not to crush the hub body and bearings. You could also try drilling a hole in it and going from there.

What lockring is it? Its not that piece of crap that comes as standard on Formula hubs is it?

I'll probably take it up to BC in the morning then... I haz no bench... Or a vice...
Dunno what it is, some cheap piece of crap that came with the wheels...

I haz a spare miche lockring if you want another POS once this one is off.

Big pair o' stilsons will do that.
If you can wait till tomorrow evenin, I'll do it for you

i know this sounds like a real bodge. If you can get someone to hold the wheel solid maybe bolted in the dropouts of an old frame. You will then needa sharp chisel make a shrp blow to make a groove in the lockring to help the chisel to grip. Then give sharp blows to try to turn it off. If it doesn't turn off you will eventually cut through the lockring. Be careful youdo not go too far and damage the hub threads. best of luck.

ha!

that is the best bike maintenance advice i have ever heard.

you should get some kind of medal for that.

Cycle with it until the cog loosens and tears the lockring off by itself... That's what's happened to all of the hub-supplied lockrings I've ever had. (Downside is that it also ruins the threads and you need to get a new hub.) Sorry I can't be more help. Which hub did it come with?

I have some Stilson's, unfortunately they're still at my ex-wife's place with all my other proper man tools... They're just Formula/System X/Taiwan jobbies... I'll take it up to BC in the morning, they always have a good chuckle when I walk in with these sorta problems... Can't imagine why?

because you are a loser?

Ha! Those lockrings are definite shite. Best of luck.

+1 to formula lockrings being gash.
