cold set, but not how Sheldon advice, there is abetter method.
you will need a "thing" that I don't know how is call, but describe, basically is a bar with threads all the way, like a big screw. A couple of nut and a spanner.
put the big screw in the drops and one nut in the outside of the drops then turn the same number of turn each nut.
meausure the space. you need to go way more than the 120mm
stop and measure again, repeat
repeat until you are spot on.
this method can be use to open the frame, just put the nut in the inside of the drops
I don't know if I had explain myself clear, so any question welcome
