that is a picture of a c-record hub. I have several friends who ride c-records on the street, and have no problems, however, they are relatively skinny guys (160 and under). They didnt come out till after your paramount though. Check regular campy record. I only weigh about 145 and have total confidence in them. I have a friend who weighs 210 and rides them daily. Records would be most period correct for your bike and are known to be more durable
