Someone recently brought this nearly finished fixed gear bike into the shop. He was very excited about the build and was anxious to add a chain. Then we asked him, where'd you get that crank? "I just took it off my Madone" he replied.
A quick look down at big ring and the rear cog revealed the sad truth, there was no way to run a straight enough chain line for a single speed chain. I told him this, then he asked "whats the solution to that?" Get a track crank, I replied. Or you can trade it fot that dirty Sanches over by the trash can. But whatever you do, don't try to take a double crank from a road bike and build a fixie around it. It's gona look stupid, unless you remove the inside chain ring. Either way though it will work like crap.

Leaving a comment on an old post, but maybe you'll see it.
I agree that taking a road-crank and applying it as a fixed/ss won't give a proper chainline with that set up, but it could be done perfectly fine (single speed only) if he was simply using a standard road frame + SS spacers on the freehub, which offers an adjustment of the cog placement for a good chainline.
OR a WI Eno Hub, perhaps?
yes, I think your right, if he wanted to use that crank for a single speed his best bet would probably be to convert his old ma done with a single speed hub. I still think the only solution for that frame and wheel set is a track crank
