I have a stock 2010 Gary Fisher Kaitai, and i have a few questions.
-I need to upgrade my brakes from the crappy promax ones to avid bb7's
-Firstly, is it possible?
-Will i need new levers? (i am using ef50 integrated ones) Will i need speed dial levers?
-Will i need new cables or housing?
-What are all the steps i need to take?
-Is it worth the upgrade?
-Is there anything else i need to know?

I dont want this to happen to me:
