Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

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.
