pretty sure the CD are the hard anodised ones - which are about 38 quid a rim. I've been told they work fine with a brakes (though a softer brake block can help).
whoops should have read on a bit further....................
no, the black ones aren't cd. the cd's look a bit like gunmetal/charcoal. plus the look unmachined because the machined surface is also anodised.
CD's ftw
