    pretty lame

    That's how they are. you can always just run the chainring on the inner lip of the crank.

    3mm chainline error is totally fine. If you are a perfectionist, it might annoy you, but mechanically speaking, its nothing to worry about.

    No problems here either. Some cogs can actually give you anywhere between 43-43.5mm chainline in the rear, so difference between front and rear chainlines could be even less than you think.

    It wasn't fine for me.. I kept throwing the chain when I'd skid and hit any sort of bump in the road, no matter how tight I made the chain. So, I put the chainring on the inside of the spider and flipped the cog on the rear hub. Now everything is straight.

    Does a chainline that's off by 3mm stretch chains a lot faster than a perfect chainline?

    I just installed my chainring on the inside of the spider, so now my chainline is perfect. I'm hoping I don't have more chain stretch problems.
