Road Bike Rear Derailleurs

Shimano Dura Ace RD-7900 Rear Derailleur: 10s - Grey (<100 Miles Near Mint ++)

Smooth shifting and wild aesthetics from the last 10 speed Dura Ace rear mech.  Its weird to see the original H.R. Geiger Alien styled derailleur become "outdated" and affordable, but this is where we are in the world.   Condition Near...

Suntour Cyclone GT Touring Rear Derailleur: Mid Cage - 1st Gen - Silver/Black (EXC But Needs New Pulley)

The Cyclone model was Suntour's first venture into the high end road market, and was a direct competitor of the mighty Campagnolo Nuovo Record.  In fact, it was lighter and better performing than the Campy derailleur!  At 195 grams, this is...

One of Campy's attempts at the entry to mid level game in the 60's to 70's. Condition Near mint VERY lightly used shape. I see barely any signs of use, perhaps even a NOS take off. Pulleys and inner cage plate are so clean it's barely recognizable as...

Campagnolo C-Record Rear Derailleur: Prototype / 1st Gen (Near Mint)
