This cassette is my lil' buddy. I have put a beating on this thing! The one piece aluminum body is light and mine is anodized red, a nice touch of bling :) This paired with a SRAM 9 speed chain and the SRAM X9 rear derailleur and shifters = Quiet Precise and crisp shifts. I Love this cassette period.
