Anyone ever have a problem with the ringle cogs? I have tried several cogs as well as chains and messed with my alignment for hours, and for some reason the cog and chain never quite seem to be a perfect fit. I am very particular about my drivetrain and I just put my new ride together and still have this problem, the chain just never seems to jive with the cog. If I'm pedaling hard everything is fine, but when you are just cruising (pedaling) you can feel it. HELP!!

I personally have no clue on this, but wonder if a break in period would change things. I doubt it, but thought I'd offer that up.
