yeah the problem is definitely the lack of a lockring tool. ask the lbs to install it with theirs if they don't sell em.

lol i don't think i made my self clear, the lbs doesn't have one of there OWN.. there both waiting for an order to come in. I asked them already, im like hey, could you tighten up my locking please. there like i would, but no tool.

i can't believe a bike shop doesn't have a lockring tool

I didn't have a bank card for years and never had a problem finding a friend to help me. Get the tool and call it a day.

+ rotofix

make sure everything is super tight.

= no slip

those bottom bracket tools work just fine and they make life so much easier

ps:

I also have a surly cog, and was having the same issue you were and had read the exact same thing about the surlys not being the best.

I got the bottom bracket tool and everything is gold now.

go to your lbs and ask them to get it uber tight for you!

Don't use the cheap lockring tool. The Park HCW-5 ($15.00) works fine. I had the same problem with my cog coming loose because I only had that 'hook' lockring tool (which is on one end of the Park tool). Couldn't get it tight enough because it kept slipping and busting my knuckles. The bike shops around here use the very expensive plier-type tool from VAR ($75.00).

Or just take it to your bike shop. That lockring needs to be really tight on there.

You guys/gals couldn't have been more helpful. Thanks for all the feed back, i guess I will be riding with no back pressure for a while (np, got a brake). Just gota wait for the lbs to get a lock ring tool...

Again, thanks for all the input.

Just have someone weld the cog on and be done with it. The threads will probably be mashed the next time you take it off anyways.

^^^ um steel cog. al hub. does not compute... your not helping

if you're going to ride in the meantime rotofix the cog onto the freewheel side. that way you won't strip your stepped threads.

also if the lockring isn't tight and the cog comes loose in a sprint the rear wheel could lock and cause some catastophic failure...

that happened to me and i skidded on my face for a few feet.

I wholey agree with making your own tools. The vicegrips ginder thing is what I did. But I've had my eye on the EAI supertool. Looks great has 15 and 10 mm wrenches and lockring and cog tool, but $150? It's on my christmas list.

something similar to the one on the right makes a good lockring tool with a little modification.

edit: ^ what he said

How can your LBS do business with no lockring tool? Are they telling everyone that comes in for a BB adjustment that they'll have to wait? It's like not having tyre levers.

All the cool shops were running lockring tool-less.

it's probably a shop that doesn't do a lot of fixed gear business and doesn't realize a BB tool does the trick

i have the 6" vise grip there. i haven't modified it and it still works great. and it was like $8 at sears.

now, is that a real poncho, or is that a sears poncho?

Well i went to a father lbs, and we spent 30 min or more setting up the lock ring.
First problem was that the spacer was too soft (the metal) so it had just been flattened, and warped.
Second, was that the chain whip never got it tight enough.
What we did was take everything off, put only the cog back on, and i went out and rid the **** out of the bike (full pressure), i walk back in to the lbs (panting) and they place the lock ring flat side first, cause they said the cog was so beefy. then they used that 75$ tool hairlessbill mentioned.

So far it hasn't come loose. I tried skidding but got nowhere.

and i got kool stops (the bmx ones)
