In particular for the Super Record models - they seem identical even in the old catalogs. Other than the bearing size (3/16 vs. 5/32) is there any way to tell the difference visually? Measuring the diameter of the races would be difficult I think. Also, will the races get damaged if they are used with bearings that are either to large or too small? What is the rational behind using 3/16" bearings for the pista version anyway? Just wondering...
