Hi all, first time poster.

Having a bit of trouble with my rear wheel, notably whenever I try to skid/put any major force down on the cranks, like a hill start for instance. It feels like the sensation of the wheel losing traction and skidding (obviously not actually skidding though) or even the cranks coming lose in the BB. I assumed it was just the nuts holding the wheel in the drop outs being loose and only a case of tightening them, which I've tried but to no avail. Any suggestions as to what it is/has it happened to any of you before? I'd investigate this further myself but I'm away from my bike at the moment, thought that getting a second opinion would be my next best option so I have some direction when I come to tackle this myself. Cheers guys.

Does the wheel actually move from its set position and get locked up against the chainstay? HTFU and torque that sucker down

loose cog/lockring. go buy the proper tools and tighten. repeat periodically.

Or get a brake and stop skidding like a ******. Just sayin.

Or or or...

"Investigate further" when you are not "away from yer bike".

Its probably what Farting Fox said.

Flatulentfox is right, its loose cog and lockring, i try to tighten mine once every week, u will need a lock ring wrench of the right size as well !

Don't worry about it I tightened it for you and now it is all better.

Don't put this off either. It wont go away, only get worse which will result in bad things happening. I would also consider rethreading cog + lockring to make sure no crossthreading has not occurred, grease if needed.

I had this issue.

Definitely a lockring/cog (stripped thread on the hub) issue.

you can either
1. get a new hub/lockring and put red Locitite on the thread (you won't be able to remove cog/lockring after)

2. velosolo has a front mtb hub converted to fixie rear hub and sells cog with 6 holes so you can bolt in cogs to the hub (prolly best way if you skid alot)


i tried getting quality hub/cog/lock ring and had it properly installed but didn't really solve the problem for me, especially going uphill at slowspeed so lota pressure on crank or skidding on very grippy surface with grippy tyres

after stripping 2 hubs, i went with #2 option and never had a problem since.

or.

you skid and you tighten the lockring and you skid and you tighten the lockring and ... #infinityloop

or

you keep loosing and forgetting things when you are drunk.
so when you drink, you need to check your belongings more often being more cautious?
no. you have to stop drinking.

or... #whatdoiknow

This guy gives the best advice. The 'drjaa knows' thread will be replacing the 'Ask Scrod' thread soon.

I must not put out enough watts, been riding with formula hubs, lockring and surly cogs for years and never stripped my hubs. One day I'll be strong.

You used the loctite, didn't you?

Nah, just my top secret tool. Grease and adequate torque.

that's a joke right?

Neither have I, my guess is threads were destroyed from improper lock ring instillation

Yes...someone suggested using loctite in an earlier post and I thought it was hilarious, so I was carrying on the joke.

^ Sorry, sometimes can't always tell. I see stuff on here that's clearly meant to be a joke, but then it turns out it wasn't.

Who uses red Loctite on a cog? I usually just weld them to my hubs.
