In the April 1984 issue of Bike Tech there are learned articles about the relative merits of various rims including the Weinmann 256 and the concave A124 and A129. They performed poorly being heavy yet not particularly strong or rigid. The star performer among wide section rims was the Mistral 120. In my opinion the Mavic Mod. 3 has the best combination of virtues and that has been my experience in practice. Indeed I feel the later, dark anodized, Module 3CD is the nicest looking rim ever. Side wall wear was not measured indeed it is not even mentioned. Ray Green, Brighton, England
