My Bianchi came with Modolo Speedy calipers, which I replaced with a Campag. set I found cheaply at a yard sale. My solution to inadequate braking was to replace the brake pads with KoolStop salmons, grease the cables, and replace the Modolo (Campag. clone) levers with Shimano aeros (they and the SunTour freewheel are the only Japanese parts I have on that bike). These changes made a huge difference. My finger reach and grip strength are both below average, and I do fine with the Shimano levers, just as I do with old Weinmann Vainqueurs.
