I am anxiously awaiting my first 29er frame, and have begun researching the build components. I have deceided to go 2 x 10, and have narrowed the shifters and rear D to either XX or X.0. The XX is a little lighter, but probably a little more fragile as well. Also not sure I like the torx required to adjust the XX compared to a allen for the X.0. The XX features cermaic bearings in the jockey pulleys compared to straight SS cartridge bearings on the X.0. The XX has a unique p nuckle movement as welll, refered to as eccentric to allow for the 36t cassettes, don't think the X.0. swings that way. Anyone have experience with either? Thoughts?
