I have a set of Zipp 202 and 303 wheels. One bike has the Campy red pads for CF wheels and the other has Zipp pads (Gray). Both work nicely and have held up pretty well. I think I like the Campy pads a little better, but it might just be I like the 202’s better. The instructions on the Campy pads give all kinds of warnings to not use on anything but Bora wheels, but not an issue for me.
I have a set of no name cheapo pads I got from Amazon, that I used on my TT bike, theorizing that I would never be screaming down technical descents on it, and they worked fine but I only used them for about 100 miles and the bike is consigned to the indoor trainer now.
