I have a nice vintage set of Campagnolo Nuovo Record brakes, but I removed them and went to dual pivots a decade ago due to the hand fatigue of the high tension brake spring and the fact that I do not ride in the drops, upper bar and hoods now.

I have heard that someone may be making reduced tension springs for the Nuovo Record brake which would really be nice as I could then use these brakes on a vintage bike rebuild, otherwise I will look at the SunTour Superbe brake but therein lies the problem of do they have enough reach (the Nuovo Record are of long reach design).

Thanks for any help suggestion is finding these springs, if they exist, or if there are other ways to modify the Nuovo Record spring to reduce spring tension.
