Help me fix my bike ( no good lockring?)

Occasionally when i ride my bike it feels like the cog is slipping. When i lock up to slow down it's done it, but its hardly noticeable, but when i began to speed up after is when its most noticeable. After it does it once or twice while moving forward it wont do it again until i lock up again. Is it a ****ty lockring or maybe something I'm unaware of? Has anyone else had a similar problem?

If you guys could help me I'd appreciate it.

Thanks in advance

What kind of cog and lock ring do you have?
Why not try and tighten them up?

Pedal forward, then tighten your lockring. Sounds like the lockring isn't on as tight as it should be.

go ride up a nice sized hill, then take a flathead screwdriver and hammer to your lockring, tighten it on, you should be good. if not, look into a new lockring/check your hub.

I have some no name junk on my bike. I am going to take it to my LBS to have them tighten it up. Im just scared of having such a ****ty lockring that it might mess up the thread. I don't know if thats possible.

Thanks

Lockrings need to be tightened after cogs are installed, and after the wheel has been ridden. If play develops, something is liable to be stripped. Especially if any of the following are crap quality hub/cog/lockring.

I have formula hubs, but how i said earlier, " I have no name cog and lockring". I know formulas will last me a fair amount of time, but considering the bike is only 1 month old i will take it to my LBS to be re-tightened. In the meantime I'll look for a decent lockring and cog online.

Thank you!

Id get a real cog and lockring and toss those crappy ones if you care about your hub.
Good cogs and lockrings are cheap. Hubs and having a wheel built arent.

I just went through the same thing with my Pista. After repeated trips to the LBS for tightening, I finally found someone who figured out what the problem was. The original shop that did the build on the bike used a cheaper cog than what came with the bike . (I assume that was to keep the better cog??? or maybe just stupid..) anyway the cheaper cog was slightly thinner, and did not sit tight against the tightened lockring. LBS gave me a .5mm spacer ring to go on the hub before the cog, to take up space... Unfortunately once i pulled the cog, the hub was stripped!!!!! this was a free fix, and had i done it a day earlier i could have saved mu hub!!!

I had problems with a lock ring loosening up and just switched to dura ace, and honestly I cant believe how loosely the cheaper lock ring fit on the hub. Save yourself some trouble and a stripped hub and try a new cog and lock ring. They really aren't too expensive.

On a forum where no one ever agrees about anything, there is universal consensus that one should always use quality cogs and lockrings on their hub. I think that says something.
