I've been wanting a brass GGTS Top Tube and I'm kicking myself for not picking one up when COV still had them in stock a couple of weeks ago! I now notice that COV doesn't even list the brass GGTS Top Tube as a "Notify Me" option ... does this mean that the brass GGTS Top Tube is no longer being made? I've signed up for notification on the stainless steel GGTS Top Tube, but I'd really prefer a brass one.
