52T/25T = 56 links (55.01in rounded up)
Whatever the maximum differnence is likely to be no more than a single link, so no big deal.
You would actually ROUND UP over .01"?
You just blew your credibility with your own post.
What if the chain stay was 17.24"?
Also cage length affects TAKE UP CAPACITY, which is the point of the discussion.
