Shimano Dura Ace 7700 9 Speed Cassette

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. Year by year, it's been enhanced, and this review is of rear mech from the 2004 model year.

Advantages: strong

...to last, which this will. This is a 9 speed model, meaning it'll work on a bike with anything up to 27 gears, but will also work fine with 24 or 21 speed systems (from my experience anyway). Once properly set up with a compatible shifter such as one of Shimano's own (there is also an LX 9 speed shifter, which is just as good value) and a half decent cable shifting is smooth, quick and accurate - you put the shifter in a gear and the mech follows properly. Apart from the more-expensive-than-it-actually-is looks, this mechs main features are its light weight (only 288g), 9 speed compatability, and a number of small but useful things that you usually only see on more expensive models, such as rubber boots to keep dirt out of the cable to keep shifting smooth. The mech can cope with up to a 34 tooth cassette, and right down to 11. The majority... Read review
