I'd be pretty comfortable ordering a 110mm BB, measuring the chainline and getting a different one if anything is off or doesn't clear. Square-taper cartridge BBs are pretty cheap and some of us end up with a variety in our parts stashes before we know it.
I'm getting an education. Just got off the phone with FSA. They said if this was a typical road frame then 110, BUT, since it has 135mm dropouts, they suggest a 68 x 113 to keep the chainline right. Doesn't seem like a big difference, but I'll go with it.
Any thoughts on quality of a Shimano UN-26 (Tourney) versus UN-55 versus an FSA TH Industries?
