Goldtec offered their glorious rings as an £800 package with Middleburn made cranks. They were logo-less.
They were available in Black or Silver.
Their sales were very slow and consequently Middleburn ended up selling some off at shows etc.
I have some of the Silver RS1's bought without logos from the Middleburn stand at bicycle expo 199something.
Their hubs are lovely. I've been using a set since the beginning and now have 3 sets of them on several bikes. They need a bit more care than Hope, but sound great and perform just as well.
