Light, shifts great, makes every stock bike feel better (unless they have an XTR stock). If you run a 9 speed drivetrain... you should probably be running this (or the XTR) cassette.
It doesn't come stock on most bikes (it's cheaper for bike co. to instal the SRAM PG970's)
Find a gear ratio you like, instal it and ride it until your legs fall off.
