Sprockets all the same?

MrSmith also cogs have different spacings i use an eai cog as it's chainline is further out than some other cogs which helps my chainline. there is a chart on sheldon brown that lists the differences.

Glad you said that. I read something about someone on here needing a 2mm spacer for a flyer to correct the chainline. That gave me a minor panic until I looked again at mine again and realised that it is fine with an EAI.
