    Sheared Off My Lockring / I.D. This hub Please

    Wow WTF, I was slowing down... NOT skidding tonight and my f'ing lockring popped off...
    The wheel / hub is only about 6 weeks old. Does this happen alot?
    Can anyone I.D. what brand hub this is?

    Thanks, Jake






    Is this what happens when I make fun of cycling caps? Jesus!

    Did you check before you started off today if the lockring was snug?

    Looks like a basic Formula/Dimension hub to me, should be able to find a lockring at your lbs.

    Lockrings usually strip off because of improper installation.

    What would constitute improper installation? I put it on myself... Im sure that I didnt cross thread it or anything. Thanks for the I.D. on the hub!

    The cog and lockring have to be screwed on very tight, and after a couple of rides the lockring should be checked and tightened down again if needed, just incase the cog got threaded on further from riding.

    OK... thanks. I guess I didnt do anything weird then...
    I even made sure to hand tighten the lockring on there (at first) to avoid cross threading...
    Tighened the lockring (with a proper lockring tool) a a couple of times on the first ride. I ride in the city so I stop / skip / skid / backpedal ALOT, and if anything was loose I would have noticed and tightened it up.

    Unfortunately, I just took the cog off and had a look... Its definately the lockring threads ON THE HUB that are stripped. The threads on the lockring itself are fine. Goddamnit.

    What are they gonna say down at BikeWorks?
    The hub should be stronger than this right?
    Like I said before, the thing is only like 5/6 weeks old!

    AAAARRRGGHH!
    Thanks again for the help / answers
    -Jake

    It even looks like the hub threads are shot in that picture. Fortunately, it looks like your hub is fixed/fixed, yes? Flip it over, install everything carefully, and tighten it down really well, and you should be in good shape. It can take a little practice to get the cog and lockring just right, and it's definitely worth checking periodically through several rides after installation.

    By the way, are you using a chainwhip and lockring tool?

    My money's going on Joytech Hub. Consider it effectively a Formula/Dimension/Nashbar/Iro/Kinda-sorta-not-really-Surly.

    At least you have a fixed-thread on the flip, so consider yourself lucky that you have a second chance.

    I'm too doped up on Lortabs to walk you through a proper installation, haha.
    It's bad when you're 19 and people consider you an "old geezer" in the current FG community.

    Unfortunately, the other side is fried from my first attempt at switching a cog, when I didnt know that the lockring was reverse threaded... I got it off alright, but killed that side of the hub obviously.
    Due to this incident, I have taken it easy / deliberately with the other side...
    Please let me know if you see anything wrong with my install ation procedure:

    1. Screw on cog / mount on bike / tighten by jumping on the pedals...
    2. Remove wheel, screw lockring on counter clockwise (by hand until it meets the cog)
    3. Tighten lockring with lockring tool
    4. Ride around, tighten lockring (repeat)

    Seems logical to me... did I forget anything?
    I always know when the lockring isnt tight after I change a cog cause I can feel it slip when I try to skid... IS THIS THE PROBLEM?

    ...from skidding when the lockring isnt tight enough initially? Is that little bit of high torque back spin from the cog enough to strip the lockring threads on the hub a little?

    I havent felt it slip at all lately and like I said, I am constantly decelerating and skip stopping when riding here in in city traffic...

    CRAP... Crap. Im gonna have to buy a new wheel tomorrow.

    That's most likely what happened.

    Try this method for tightening the cog, works much more effectively than jumping on the pedals.

    You have to grease both the cog and cockring liberally.

    If you can source a very similar hub you can just switch it over and re-build the wheel.

    Yeah... I will probably buy a new wheel tomorrow cause I cant stand to be without the bike right now!
    I suppose the "lemonade" to come from this lemon of a situation is that I can try and learn to build a wheel!! Thanks Peabody...

    You can't even install a lockring properly. Perhaps this is not the best idea in the world.

    I agree it was probably the lack of grease. You probably didn't get the cog on tight enough in the first place

Jabba's right, if you don't know what direction the threads travel on a hub and you're using techniques like jumping on pedals to tighten down cogs maybe you shouldn't be building wheels yet.
