On a recent visit to my favorite bike shop, the owner located a stash of old N.R./S.R. derailleur pulleys. I was hoping that they would fit on an old Record (steel or brass) derailleur.
No such luck. The Record was designed to use smooth (no tooth) steel ball bearing pulleys. The inside pivot arm has a tiny tooth that holds the pulley cones in place.
Anybody have a set or know of equivalents? N.R./S.R. pulleys could work if the tiney teeth were filed off ... but I'd rather go with originals.
