The flame war between shimano and sram is dumb. All you sram haters, google shimano failures and you will get all kinds of people saying this: "I bought this XTR derallieur, paid a ton of money, and it broke the second time I used it". Same story the other way around. Bottom line, stuff breaks, buy what you think looks cool. It has a warranty, so stop being dumb. For the record I have had top end shimano and sram forever, and both have given me all kinds of problems. Why? Because stuff breaks. Deal with it.
