The Elusive Mavic 840 Derailleur...

is finally mine. I managed to snag one on ebay for a song -- literally at 25% of the cost it should have gone for. Go me. Click for a bigger picture.



Its got the usual array of scratches and scrapes. I tore it down, cleaned it, and rebuilt it. Its very smooth. Its about half an ounce heavier than a Shimano Ultegra 600 rear (RD-6400), so I won't notice its extra weight. Now I just need to mount it up, set the limits, and see if I can't get it working on a 9 speed setup. It has a ton of range, so I don't think its going to be an issue.
