so i found my rear formula locknut(the inside one) cracked when i was cleaning up my bike
but the worst thing is that the thread also messed up, i tried to put in a locknut through the thread and it won't go through...

so do you think i can fix this? or i need to buy the new thread? if so how much would all this cost and where can i get them?

thank you

and here is pictures

the locknut that i was talking about


and the thread that got messed up

have you actually ridden this thing yet?

yes i have, plenty

A shop might be able to fix the thread with a die...if not the whole axle will need to be replaced.

where can i get the axle? do you think lbs would sell it or at least i will be able to order it?

thank you

typical nub mistake for a typical nub.

happens to the unexperienced and experienced alike. lots of threads on this.

Hey, this just happened to me, too! 'Cept I didn't mess up the axle. Here I thought I was the only nutcracker.

Yeah, this is a common problem with Formula nuts. I don't think you'll have any problem with the threading on the axle if you just stick a new nut on there. You won't need to cut new threads or anything.

Remember, the aim is to get it tight enough to not slip and no more. Unfortunately, the only way to usually learn this lesson is to ruin some bike parts. Be thankful, a track nut is pretty cheap.

These are the types of things I pick off trashed wheels I see on the street or where ever. Yeah, I'm trash picker, what I can say.

heh, that's funny i had the same problem. Literally identical except my nut just cracked in half not into 4. The threads did get a little chewed, but the guy at the shop said he forced it on, and it would actually hold it a tiny bit better and not do any damage. Just go to the LBS and get a new nut. problem solved.

I did this as well, but no damage to the threads here.

+1. When I started at the shop, I cracked more nuts and ripped more heads off bolts of bikes I was assembling than I'd ever care to admit. I guess I can say at least it wasn't my stuff

That's the right one, and it's also long enough to allow for spacers for a 126/130 rear end.

i used to over-tighten my nuts until the same thing happened to me. it was on a formula hub, too. i don't wrench on them so hard anymore.

thank you people
sorry for the trouble

damn I just did this yesterday on my spare wheel and was wondering what the hell happened. the weird thing is it actually cracked when i was wrenching the wheel on. I hadnt adjusted the nut in weeks.

does anyone know if this surly locknut would work for rear formula hub?
it looks the same to me
i went to my lbs today and they force the axle/thread and it works! however the locknut are not available so i have to buy it online, that is why i am asking this question right now

thank you,
Rae

yeah the surlys work. your lbs should be able to get them for you.

This happened to me when I was 5 miles out of town on highway 1.

It was a bummer, man.

I busted the same thing on my formula wheelset. But not as bad ad you. I just glued it and locked the wheels down tight. Hasnt moved since.

If I were you Id take it to a shop and ask for a replacement part. If youre lucky they may even have one laying around and give it to you.

you shouldn't bust a nut on your bike.

i'm sure you'll get it cleaned up, though.

yeah thats not a nut to begin with, just a washer.
I would give $50 to the first person that actually broke a nut, not the lock washer.

Find out what thread it is, and you could just take a die to the axle, but in reality you should just buy a new axle, because the grain of the thread on the axle is now hosed, and no longer has it's structural integrity.
