Shimano 600EX RD-6207 Rear derailleur: Overhaul service assembly

1984-86 version of the 600ex rear derailleur. Hopefully yours won’t be so difficult to work on!. Nice information on this derailleur on the Disraeli gears website aswell as velobase. Though Velobase indicates that the bolt sizing is 5mm, it is actually 6mm as indicated in the video. Interested in bike parts and accessories. Especially quality made parts. Enjoy history of cycling too! This is what I like to bring to my videos and to share my slim knowledge with you.
