Abici Bikes Time Machine Road Dura-Ace

Advantages: Top of the range "bling" rear mech
Disadvantages: 9 speed "only", superceeded by RD-7800 10-speed version

...I bought this rear derailleur to replace an Ultegra mech when upgrading my bike from 8 to 9-speeds (well, 16 to 18 speed really with my double front chainset). Apparently, this mech is also compatible with 8-speed systems, you just need to change the cable mounting position. Dura Ace is the name of Shimano's top of the range group of bicycle components, or "groupset", for road race bikes, and the 9-speed 7700-series was introduced to the public in 1997 after Shimano sponsored riders using Dura-Ace 7700 series equipped bikes in 1996.
