Shimano has a line of bike parts called Yumeya which means "Dream Workshop" in Japanese. This high end line of Shimano bike parts will surely make all of your bike buddies look twice.

One bike europe said this:
The after market kit includes amongst others carbon rear derailleur plates for RD-M970/971 (saving 11 grams), titanium cassette sprockets (saving 15 grams for a set of 17/20T), titanium bolts (-25 grams for the total set), a chain with hollow pins (-10 grams).

Here is the manufacturers website

The parts have a beautiful silver and gold finish and obvious functionality of appearance.  If the parts are anything like the high end Shimano fishing reel I own then they are awesome!
