From <http://sheldonbrown.com/harris/derailers-rear.html>:
"Low-normal vs High-normal
Most rear derailers are pushed by a spring toward the highest (smallest)
sprocket, and the shift cable pulls them toward the lowest sprocket.
Shimano "Rapid Rise" rear derailers ( XTR Rapid Rise, Nexave T400,
MegaRange Rapid Rise and Tourney Rapid Rise )work the opposite way,
springing toward the lowest (largest) sprocket. This system provides
slightly better downshifting, but can be confusing to a rider who is
accustomed to high-normal derailers. Either type may be used with any
contemporary Shimano shifter, but if you use a low-normal derailer on a
shifter made for high-normal, the indicator numbers will read backwards,
and you will have to shift in the opposite direction. However, if you
use a Rapid Rise derailler with bar end shifters, both shifters will
shift in the same direction ( up will be higher )."
