And I’ve never seen them since!Good luck in your quest, they seem to be like rocking unicorn poop. @ibbz owned the only set of Quarz I've seen outside of the catalogue. I've been looking for them myself, along with a set of original chainrings to complete my Quarz set up. No luck as yet.
I guess the rise of the V-brake at the same time as Quarz came out, as well as the subsequent Sram takeover means not many were made/sold?
