Racers have the correct reach for a 700c to 650b conversion --- if your 700c Riv had relatively tight clearance. For example, my Riv Road Standard barely was designed for short-reach brakes and barely cleared a 700 x 28 tire. The 57-67 mm reach of the Paul Racer is perfect for this application. If your Riv has the clearance for a tire larger than a Jack Brown, then the Racers may not have enough reach.
To be sure, you can measure your Riv. http://www.sheldonbrown.com/calipers.html Add 19 mm* to your measured reach. (*difference in radius between 700c/622 and 650b/584) If this number is between 57 and 67 mm, the Racer should work. FYI, the Tektro R559/Silver brake has 55-73 mm reach (a bit more if you need it) and Dia Compe 810s have 81 mm max reach.
