I recently bought an '89 Schwinn Tempo that was converted to a fixie. I got it on the cheap because the guy had the rear wheel stolen and didn't want to replace it. I was able to get a decent Weinmann wheel w/ flip flop hub at the local bike shop (Bike Lane, Chicago) but the cog is 3mm out of alignment and needs to be moved outward. I cannot adjust/flip the crankwheel and I do not want to replace the entire crankset or bottom bracket. That being said, I feel like my options are to install spacers on either the axle or the hub.

Spacers on the axle will push the wheel away from center, but I do not have a rear brake to worry about rubbing against, nor any intention of using the other side of the hub in the near future. Installing ships on the hub should just push the fixed cog out to the location I need. Do you guys think this will work?

Thanks!!
