They will not match a good modern rim of course, but still a better choice than I believe those old Wolbers are pretty flimsy in comparison to the Open 4s which were a big improvement in rigidity. That contributed to the early failure I mentioned in my posting above.īoth the hard anodizing and the later ceramic coating (a real brake pad eater) were dropped relatively soon.Between the two choices the Op has has stated I'd still say go for the Mavics.

The thick annodizing was more brittle than the underlying aluminum and, as the rims flexed under load and it wore off the brake tracks the residue cracked and acted as stress raisers.

What it did do was make them more crack prone. Mavic claimed it made the rims stronger, stiffer and more wear resistant. Note: this is not he later ceramic coating. The Open 4CD rims were, AFAIK, Mavics first use of "hard anodizing", which is what the "CD" meant, which is thicker than the very thin color anodizing typically used.

You will occasionally need to true a bit, but they are easy to tune.The Open 4CD rims were, AFAIK, Mavics first use of "hard anodizing", which is what the "CD" meant, which is thicker than the very thin color anodizing typically used. There are better rims out there now (stronger and lighter) but the open 4s were a decent set in their day. The difference in price of the two sets on the used market is probably no more than ten bucks so it is not like you are really going to cash in on selling the better wheelset. I'd put them on as my best riding wheels and sell of the others or keep as spares.

I rode thousands of loaded touring miles on open 4 CDs with no trouble at all.
