Only two I have opinions on are the chan and the shifters. I always buy SRAM chains. The powerlink just makes it way too convenient. As for the shifters I would go with the SRAM as well. After riding SRAM for a while I don't ever want to go back to Shimano. I rode my sister-in-law's bike a few weeks ago and it had lx shifters. I got so tired of having to take my finger off of the brake lever in order to shift.
