So I just put on a new 20T chainring which I downgraded from a 22 on my XT crankset with a 32 in back. Now, when I pedal in the granny, I'm getting skipping. It looks like the teeth are not matching up on the chain. Is the ratio off now? Is there a way to fix this problem?

Where did you get a 20T chainring for an XT Crankset? I thought 22T was the smallest for a 64 BCD.
I believe this is true, (unless there's some custom/special set-up outthere somewhere).
Compact drives (58 BCD) are the only one's that can run a 20T small. (Or is it an 56 ?)

Where did you find a 64 bcd 20t chainring? I have a 22 on my bike and it seems that the chain is right on top of the chainring bolts. I use a 34t big cog in back to get the same thing you are after. A crazy low granny gear.
... chain is right on top of the chainring bolts.... crazy low granny gear.
With 9-sp (34 rear cassette) I've seen problems getting a 20T front to work well.
8-sp (32 rear) with the right nut-bolt combinations can work w/ 20T front.
Then again - I haven't seen a 9-sp compact drivetrain. There might be some special made somewhere, but none that I've ever heard of. [Edit] I takes this back, There's plenty of 9-sp compact, I was thinking purley Shimano [/Edit]

I think you mean; "It's made for a compact crankset". I doubt they made one ring just for you, unless youâ€™re a sponsored racer.
Then again a sponsored racer rarely goes in the small ring, so ....
