What size for a single chainring? 113?

I know I saw this on a thread here but couldn't find it. I hope my marriage can survive yet another R20 upgrade! :notamused:

Here is a review of that BB (http://tsaleh.blogspot.com/2010/01/review-velo-orange-grand-cru-threadless.html) I would shoot him an email and get his opinion. He does have a Twenty so is familiar with the idiosyncrasies. It appears that he did not think it would work. It may be possible if you can reduce the width of the BB.
