Hi, I have a couple of cranks hanging around, FSA K-light and a FSA Force ( all compact) and would like to try a 53/39 setup , But when I checkout ebay and other sites to buy all the 53/39 are a 130mm bcd and mine are 110 mm , not sure what those #'s are indicating ... ???? Will a set of 53/39 FSA 130 mm fit my FSA cranks currently 50/34 110mm ********************
