Shimano Dura-Ace 25th anniversary (7700 SS)

Shimano Dura-Ace 25th anniversary derailleur (7700 SS) main image

To celebrate the 25th anniversary of the first Dura-Ace groupset, Shimano released a special commemorative groupset including this 9 speed derailleur. Note the subtle golden ‘25’ written to the left of the Dura-Ace logo.

Other differences were a titanium hanger bolt and cable clamp bolt, stainless steel pivot points and (for some reason) black pulleys with white writing on them.
