This is a beautiful derailleur. Here's why I love it:
- It is a clear derivative of the, very tidy, Gian Robert Competition (or perhaps the Argentine Gian Robert Competicion).
- The lettering on the outer parallelogram plate has a pleasant Art-Deco look.
- And then there are the 'arabesque' flourishes - which are a pure steal from the famous Shimano 600 EX Arabesque.
