What does the Total Capacity spec mean? For Shimano's RD-M760-SGS it's 45 teeth.

Edit:

Found the answer:

The total capacity is calculated by subtracting the size of the smallest chainring number from the largest chainring and adding it to the difference between the largest and smallest cog in the rear.

This thread has the best title I have ever seen on a message board. In fact, I believe someone needs this as their custom title.

"Derailleur Spec: Total Capacity"

If the Japanese made a bicycle racing videogame, this is what it would be called.
