Creaky crank

I just replaced the smaller chainring on my crank, and now when I put a lot of pressure on the pedals it creaks every revolution or so until I get up to speed... after which it seems happy. (No problems when I'm spinning.) I thought I tightened the chainring, but I'm wondering if it could be something else.

Thanks.

Obvious questions:
- Did you grease the chainring bolts before re-installing them?
- Are you *sure* that you tightened them up properly? It's easy to have a little play (enough for a creak, certainly), particularly if you don't have the right tools.
- Are you sure the creak is coming from the chainring? Other possibilities include: pedal, crank arm, and bottom bracket. If you've messed with any of them, then they are also prime suspects, creak-wise.

-I greased with oil, not with grease... Mr. Obvious wants to know if that could be the problem?
-Pretty sure. But I'll re-tighten 'em after I grease them.
-I didn't touch the pedal, crank, or bracket, so I hope to heck it aint any of them.

I know this is an obvious question... but is it only when using the new chain ring you get the clicking?

It seems to me that if it is only the smaller ring, then it does sound like the bolts holding it are not tightened enough.. or you have differing metals in contact with each other and they need to be greased.

However, if it is on all the chainrings your problem could very well be cranks, or BB.
