Stripped locking

I've managed to mangle a miche lockring when trying to remove it from my hub. My tool slipped and mashed the slot on the lockring. Any tips for removing the lockring or is it a job for my LBS?

Doesn't it have multiple slots? You could try a flat head screw driver and a hammer to tap it loose.

I've fucked all the slots at one point or another so they're all rounded off. Might try the screwdriver but not looking promising

Just make a new slot with your flat head screwdriver and hammer :0) Just concentrate so that it doesn’t slip out on each whack. It’ll spin out in next to no time.

Yeah just waiting on some replies from LBS but I'll probably get bored one afternoon and have a go myself

At least you can learn from this - Miche lockrings are made of cheese.

Just buy a Paul Components lockring and you’ll never have this issue again

I think that's offensive to cheese

Source a large locking/mole wrench?

Tried a locking wrench and the f*cker is too shallow to get a good grip. All the teeth on the lock ring are totally fubar. I've got a couple of punches I might have a proper go with tomorrow when I don't need to worry about waking the neightbourhood with swearing. Destructive methods of removal are definitely acceptable now

Drill a hole about 4mm or so in the lock ring and stop before it breaks through to the other side then give it a wallop with a hammer and punch. That should break it and pretty much just fall off without damaging anything else.

This. Or whack with a dead chisel on either side.

So drill from the top then hammer?

Njs stamped dura ace lock rings are pretty cheap. Never had any issue like this.
Worth spending few quid more.

If a Miche hub you'll need to go with Phil Woods, Campag or anything else with the Italian thread.

I have bought an own-brand Italian-threaded lockring from Condor before.

Dropped the wheel off at my LBS today. Sadly don't have access to a drill and don't really want to be responsible if anything goes wrong. Found a Campag lockring on Condor's website for not stupid money so that's on the way. Was the cheapest Italian threaded lockring I could find that wasn't just the same one that's caused the whole incident.

LBS (Recycle-a-bike Uxbridge) managed to destructively get the lockring off. Have ordered a Campagnolo replacement. I've noticed when trying to hand tighten the new lockring I get about halfway through the threads on the hub and then it becomes really hard to tighten more. Is there something wrong or should I just use a lockring tool to crank it tight? Don't want to mess the hub up.

It's meant to be tight or it wouldn't stay on! Have a look to see if the threads are damaged

Usually I've been able to finger tighten the lockring all the way to the cog. This time it gets about halfway before needing the tool to get it any tighter. The threads look uniform aside from some scuffs around the top from trying to get the previous lockring off

Any chance that’s why you couldn’t get the previous lockring off? No comments from LBS on the threads, etc?

Previous lockring was cheese. LBS hadn't a clue why it got so stuck. Tightened the new one in place and went to the shops today on the hubs and I'm happy with the ratio I've got. Threads look pretty good to the eye so I'm just going to hope it works if I ever need to change the sprocket.
