    Drivetrain creak from only 1 or 2 cogs

    I'm running a 3x10 Shimano XT drivetrain. Lately I have developed a creak while pedaling that only happens in one cog when I'm in the granny ring (#4 from the lowest, I'm not sure what tooth cog it is). If I'm in the middle ring, I get the creak from #4 and #5 from the lowest gear cog. I haven't noticed what happens in the big ring, I'm not usually on that end of the cassette when I'm in the big ring. It's hard to trace the source of the creak, but it only occurs when pedaling and only on those cogs. The creak corresponds to the power stroke from each side. My oversimplified remedy that I'll try after winter is to install my new cassette and chain. But in the meantime, I wonder if anyone can chime in with some ideas of what could cause this. Thanks.

    The rivets on the cassette that hold those rings to the carrier.

    my AM steed (1x10) has developed an annoying creak also... f$#ker only appears 30mins into a ride though.... Had better half's uncle (owns an lbs) look into it... he removed the BB & couldn't see anything wrong, put it back together and the creak disappeared (until 30mins into my next ride!?)...

    found this online =>>> http://www.bicycling.com/maintenance...-bracket-creak

    stuff is beyond my skill level (and tool level) so am gonna ask him or Father-in-law (who's a whiz also) to give the checklist the once over...

    That makes sense to me, thanks. That would explain why it only happens on certain cogs.

    I can't explain the timing thing, but the article has good advice about checking the seat rails. On a bike years back I had to regularly drop some lube into where the seat rails mounted to the saddle or that sucker would creak. Chainring bolts are easy to check too.
