    Rear Cog~!!!

    Bike is brand new - bought it and rode it for 2 days and it was fine - moved to LA, shipped the bike down here, now there is a constant (not loud) sound coming from rear cog

    it's not because of weight - i flipped the bike over and spun the wheels and heard the same sound

    it's not exactly a clicking sound, but i'm guessing it suodns like the chain is rubbing against the cog - but it was fine when i first rode it~!

    Single speed or geared bike?

    Check to make sure that the rear wheel is still completely seated in the frame's dropouts.

    If it's a geared bike, see that the rear derailleur pulleys are parallel with the frame's plane -- it's possible and likely that the derailleur hanger is bent, causing the chain to be out of alignment with the cogs.

    Is the chain lubed? Maybe it took on a small amount of corrosion during shipping? Lubing it would fix this in a hurry.

    Anyone else have some more thoughts?

    Try easing up on the chain tension a touch.

    +1 I'll bet the rear shifted and tightened the chain during shipping.
