Problem with cog?? WHY?!
Hello 
i seem to be having a problem with a cog on my fx. when i ride and stay pedaling hard, like up a hill, the cog/chain slips foward once only. after that everythings fine until i skid, then my cog feels like it slips backwards once? it seems to slip in the direction where i apply pressure to, but it only happens one time until i apply pressure in the other direction. HELP??

Hey,
Note you can feel the same weird sensation if your hub axle is loose. I am not talking about the nuts that fixed the hub to your frame. I am talking about nuts that fixes the hub to the axles.

I had the same trouble and was having the problem even after I applied locktite. (don't do this) I discovered my hub was loose this way. So ends are moving in and out as I lock and stuff.
Too bad I have a sprocket that would never come out.

Some of these suggestions are extremely unlikely. As mentioned above, the cog and lockring are almost certainly loose.
Remove, grease, and tighten both very well. Make sure you have a chainwhip (or rotafix) and a lockring wrench, or you may not get them torqued up properly.

Anybody who says it's NOT the cog and lockring being loose is wrong. This is official.
Take both off. Put the cog on with grease on the threads. Tighten the **** out of it. Put the lockring on with grease. Tighten the **** out of it. Ride up a hill and put no backpressure on the cog. Retighten the lockring. Now you are good.

Ha is Bike Forums the first site that pops up when you type in "slipping cog" on google? I haven't been around here too long, but we get one of these every week haha.
