How long did your cog and lockring last?

Nagrom doesn't ride bikes he hangs out on the interwebs all day, if I were you I'd true tension the wheels tighten the crank bolts grease your seatpost headset and hubs, and the cog and locking when you replace them. I have Had a decent experience with my surly cog and lock ring, though they may be a little expensive for what they are. Keep in mind your stock chainring and chain are 3/32 so if you replace the cog or add a freewheel and the replacement is 1/8th inch you will have to buy an 1/8" chain, you can keep the chainring you have and I won't really make a difference.

I believe the stock Kilo cog is the exact same thing as a 3/32" 16t Scrodcog, at least in my experience. Stock lockring is also steel. I don't think either needs to be replaced immediately. They should be removed and reinstalled with grease, as was already suggested.

Thanks for all the input guys I will def be greasing everything when the bike comes and ill inspect regularly. If I suspect issue then I will definitely be replacing the cog and lock ring. I guess ill make a decision when I see it rather the worrying and buying one before the bike even gets here.

Well there's an easy way to tell if the cog and lockring are steel or aluminium. See if a magnet sticks. If it doesn't, get a scrodcog and lockring. Dun dun dun.
