With that crank design, you can't use the 42-tooth. It's bolted to the bigger one.
My chainline worked out fine because I had a freehub rear wheel, and a bunch of spacers (forte conversion kit).
Dirtdrop,
where can I find a 22 tooth cog (don't know what EAI means)? I've searched without success. I'm running 52/20, which works, but I'd prefer a 22 for longer rides, especially with this bay area wind.
