I am building up a bike and have the opportunity to use just about any setup.

I currently have some parts: Truvativ Holzfeller 165 cranks, ISIS BB, and e13 SRS

I have used XTR with no problems for years....I am considering SRAM trigger shifter and der setup (I need only a shifter and a rear derailleur and chain and cassette)

I am not that hard on parts.

I don't care if its 8 or 9 speed
