I suspect a lot of the fuss about SSC rims is just mainly about the "SSC" labeling that supposedly ties it to what the pros were actually using in the big races. I would not doubt if it turns out that the Mavic 330GL or maybe even GP4 rims are very similar to the SSC rims anyway and one would not notice the difference when riding them back to back if one takes off the decals from the rims....
But if you can afford the 3X price usually asked for SSC rims, why not!.....as they are quite the iconic Mavic rims to put on most 80's C&V bikes...
I kinda liken it to the difference between Mavic 801 and 851 SSC RDs..... Same thing but one looks uhmmm....."plus de fantaisie"
