I just did a search here, in a bunch of forums and threads. Then I spent way too long googling. Can't find the chart. I
can find lots of threads with people who have had the "problem" and are also curious why Shimano does this. But no answers or charts. Ugh!
This is a common post on the subject.

I haven't had a chance to actually install the 110mm BB, however something does look odd to me. I noticed the drive side spindle on the UN-55 is the same length for both the 110 and the 107, while only the non-drive side is longer on the 110. Correct me if I'm wrong but that is still going to leave me with the same issue I was having, only now the non-drive crank arm will be further out.
Am I missing something here?
