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.

Msngr

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

don't loctite.

and after a few rides, maybe less... tighen lockring again.

grease the threads unless you don't ever plan on changing cogs. been there, done that.

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.

jamey

sorry if this is a stupid question but what's the point of the rag?

xthugmurderx

to not scratch up your bb shell with the chain.

jamey

yep, stupid question.

explody pup

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.

jamey

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?

xthugmurderx

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.

xthugmurderx

was that an insult? i know how to tighten a lockring. damn emotion lost over the internet.

1. Tighten with 1/8 inch width chainwhip (w/ greased lockring threads, yes).
2. Tighten Lockring on with Hozan Lockring Pliers (w/blue locktight).
3. Fahgettaboutit.

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 prefer to use anti-seize but grease works fine.

/\ please tell me you don't ride 32/17.

32:17

I don't...

it is now 34:20... on my mountain bike.

49:19 on my road bike.

humancongereel

wow. even so...talk about spin.

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.
