cog slipping**********?HELP
Hey,
I just built up a winter fixie beater and when i ride it, the cog seems to slip when im stop using the pedals...its seems like it is not tight...i checked and its pretty tight so im not sure why this is happening....It slips when i stop and then when i start to pedal forward, it does the same thing...its quick, like it doesnt happpen continuously when i ride, just the first pedal stroke...is it just my lockring and cog arent tight enough? thanks for advice

Ride it for a little while without applying back-pressure (supposing you have a brake). Then try and tighten the lockring. Repeat this process a few times. If after a while the slipping still occurs I would guess that some threads are stripped.

what's with this ride it w/ no pressure business....I don't get that...do not ride the bike...
take your wheel off immediately....take off lockring and cog..check threads...grease, re-install...do it right this time

Make sure your chainring is on right. I was in a rush one time and accidently put the chainring on backwards where it had no grooves for the bolts to sit in. Felt like my cog was slipping when I would backpedal/accelerate just like you but took me a while to figure out what I did. Felt like a dumbass too.

I am 99.9% sure it's the cog and lockring. Tighten the cog as tight as you can, use any mechanical advantage that you can think of(breaker bar), you won't over tighten the cog. When I started out I used to place the front tire against a wall and stand on the pedal quite hard to make sure the cog was tightened properly. Once again, it is nearly impossible with common hand tools, no hydraulics allowed, to overtighten a cog. Then tighten your lockring, make it pretty f'ing tight. Not like putting the top of the peanut butter jar back on tight, but " My Park wrench has broken the skin" tight and you won't have any more problems. Before you do any of this check to make sure you haven't stripped all the threads form the hub.
