And assuming available ERDs are correct. You can get three or four different ERDs for some old rims, like Mavic MA2s -- from different sources, none directly from Mavic.http://velobase.com/ViewComponent.as...e-837eb8b21b0e I take the average. Then I try to find some modern rim with the same ERD -- which is not easy because everyone is trending to deep section or aero. You usually end up with some boat anchor from Sun or Alex -- or you pay through the nose for some modern clone.https://www.universalcycles.com/shop...4&category=139

Finding a replacement rim has also become more difficult for a bike with
26-inch wheels. Newer mountain bikes usually have 27.5 or 29-inch
wheels, so for the typical supplier the selection of 26-inchers has
declined.
