    Lockring question

    So first off, I'm fairly new to fixed gear bikes. Now that that's out of the way, I noticed some slip today and realized my lockring was loose. I have a 3 mile commute before I can stop at the LBS after work. Will I be creating any damage by hand tightening it as much as possible and riding to work before getting it properly tightened?

    If you like to live life on the edge and you know the cog is tight, you can use a flathead screwdriver and hammer to tighten it again. Probably your cog has loosened a little bit, though. Try and tighten that as much as you can before touching the lockring.
    Assuming you have brakes and trust yourself to not apply backpressure, you should be good.

    For cog tightness, you could always loosely rotafix it if you don't have a chain whip handy, and then tighten the lockring with a flathead screwdriver and hammer (also lightly, being careful not to totally **** **** up).

    I'll leave it up to someone else to post the link for how to rotafix, I don't know what it is off-hand.

    Yeah I thought about the screwdriver but, decided against that. I am running a front brake so that will most likely get used tomorrow. Thanks for the help.

    I actually just came across that rotafix link while searching, I may give that a try.

    Put the lock ring in your pocket until you can get it properly reinstalled. In the meantime, use your brake to slow down. You'll be fine. There are people out there riding without one. I rode without a lockring for a year with a rotafixed cog with no loctite and had no problems. The lockring is not critical. As long as you rely on your brakes for stopping and not your legs, the cog won't unscrew.

    I'd take the lock ring off and use the brakes. Leaving the lock ring on loose and skidding seems to me it would cause some damage. If you take the ring off and try that, it just unthreads and rattles around.

    ^ This brings up another question then. It slipped once while pedaling forward, from a stand still not just from backpedaling. Is that still from the lockring being loose, or another issue?

    um...bad? stripped hub or something? i dunno maybe there was just a tight spot on your hub and u didnt get it on all the way.

    but every time the cog tightens, tighten the lockring too.

    I found that after installing a new cog, it will slip forward during the first steep climb no matter how much I torqued on it in the shop. I have a steep hill by my house. My procedure for installing the cog is spin it on. Forget the lock ring. Ride the brakes while pedalling slowly down the hill. Climb the hill. Finally, put the lock-ring on tight.

    that was your cog slipping.

    what likely happened is that your cog wasn't tightened down thoroughly; after riding a bunch, you tightened it down further, which then meant that your lockring was not tightened down, which let it loosen further. you noticed the lockring is lose. you applied a bit of backpressure, and your cog slipped back a bit; then you noticed it slip forward again when you applied fore pressure.
    the hipster myth.

    i practice vagabondery.

    ^^ queerpunk is right. Your cog is slamming back and forth between engaged-with-the-lockring and engaged-with-the-hub, and every time it does this you will feel like your drivetrain is slipping. Tighten your cog and lockring up quick before you strip your threads!

    you know, also check your chainring bolts. to be honest, the slipping thing from the cog might not be the problem, it could be that your chainring slipped because the bolts are loose, and stopped because the crank held it on. recenter the ring and tighten up, tighten and lube everything up, and see how it goes then

    Thanks again, tonight I'm going to go top to bottom and make sure everything is tightened up. Probably something I should do regularly anyhow.
