My wife's Raleigh mixte had a set of Shimano 600 sidepulls on it when I received it. The frame is set up for centerpulls with a brazed on hanger in the rear. The former owner had simply zip tied the rear brake cable to one of the two top tubes. I bought a set of Weimann sidepulls for $10 and restored the original setup. It looks much better now.
