a 48t ring is the same size on the outside what ever the bcd is. With a 130bcd chainset though they'll probably be designed for double rings so if you put a 48 on the outside it will seem like it's further away from the chainstays.

It was the spider that was catching rather than the ring itself I just listed the ring sizes used for completeness.
