Bottom Bracket Spindle Length

[Alex]

I'm in the process of a build (collecting parts), and I have a question about the spindle length for bottom brackets:
Would it be catastrophic if I used a 68 x 113 mm BB, instead of the factory size of 68 x 110 mm? It would only be a 1.5 mm difference on each side of the spindle, correct?
I know chainline is critical on a SS, but how much would it affect a geared bike?
