    fixed gear: getting the lockring on tight.

    i screw the cog on the hub

    then i screw the lockring on

    then with a lockring tool (the same one as for a cup&cone BB) i tighten it down as hard as i can

    should i do more? such as loctite or more leverage?

    i know you gotta get it really tight but thats about all i know.

    make sure you are chainwhipping (ooh. dirty.) the cog tight first.

    don't loctite.

    Your cog + lockring will also get on tighter with grease.

    If you don't have a chainwhip, use the rotafix method to get the cog tight. Put a rag or something between your chain and BB shell when you do.

    Nah, I wasn't very clear in my post above. If you haven't already, read up on rotafix. The rag will make much more sense.

    this whole time i thought rotafix was when you put your bike facing forward against a wall and pedal forward to tighten it down. what is that way called?

    time consuming? cutting corners? in a hurry? i dunno, i just think that is kinda stupid, unless after all that jumping on pedals you plan on taking the wheel off and tightening the lockring again anyways...i actually saw a shop owner do it that way. I went in on a whim, saw they had a khs, went to test ride it. before i got literally 2 revolutions away, the cog slipped. i brought it back in and told the guy that he should probably not let anyone else testride it until he fixed that...he asked me to hold the bike and proceeded to jump on the pedals. i left before i could find out if he did anything to the lockring. i doubt it.

    Why would you have to take off the wheel to tighten the lockring?
    You just have to use the proper tool for the job. Maybe you should have stayed to see how to tighten a lockring properly.

    that is your solution. Still put your lockring on though.

    It seemed like you were questioning the actions/intelligence of the bike shop employee. Whether or not that was an insult is up to you, however you did make the assumption that he did nothing to the lockring after you left. I don't see anything wrong with tightening a cog and lockring while it is on the bike. It can be safe, effective, and much quicker than removing the wheel. I've never done it this way because I tighten my cogs properly before mounting the wheel.

    you may know how to tighten a lockring but this still makes no sense to me
    i just think that is kinda stupid, unless after all that jumping on pedals you plan on taking the wheel off and tightening the lockring again anyways
    I prefer to use anti-seize but grease works fine.

    Not going up singletrack at a 15% grade. Coming down, yes, but it's not so bad. It's pretty steep here in Southern California; I don't really ride anything that approaches flat around here except a small part (~4 miles) of my 20 mile road commute.

    I do change my mountain bike gearing to 34:15 for 'cross racing.
