Hi,

i have an FSA Vero dbl crankset on a 68mm x 103mm (JIS) BB. I'm keen to replace the BB with a Shimano UN55 BB, but the closest spindle length they do is a 107mm. Any idea if the 2mm (107-103/2) is going to cause issues with chainline?

I don't tend to ride cross-chain (always avoid the 2 opposite end sprockets).

Thanks
Guy
