Okay now this freehub body damage info has me worried. I've read a number of different BF and Road Bike Review threads about it.
I'm wondering why that AC kit says it's not compatible with 6700 cassettes. I found this page with the clip kit:
http://bdweb9821m.bluedomino.com/store/page13.html which says it will not work with 7900, 6700, 0r 5700 cassettes. Is it only made for like 6600 and 5600 level stuff?
