One or two things puzzle me about this.  Why do you all want to do  
this?  Is it a matter of having a single chain ring crank in stock and  
wanting to find a use for it?  A perception that a double crank is  
somehow fussier or more difficult or more complicated?

I can certainly understand in the case of a single-speed, fixed gear  
or internal gear.  I can even understand buying such a crank specially  
for one of those applications.

But why a 1x8 or 1x9?

I don't think you save anything on the cost of the crank, and if what  
I read is correct, in many cases - obviously not all - you end up  
needing to put a front derailleur on it just to stop chain throw.

You certainly don't win anything in terms of chain line, if such  
things matter to you.  And even employing super wide range cassettes,  
there's no way to match the range or spacing of a double.

You do get to use some very pretty chain guards that you couldn't use  
if a derailleur were in the way.  Is that it?
