Oooh...I hadn't seen this. Looks like something my middling mechanical skills can deal with. To Jur's pont, if a derailleur adjustment or brake adjustment is needed, that much I can handle.

Okay, looks like I can get the Kinetix wheel for $40 bucks new, yay! So would using this wheel spacer and then using a cassette spacer for the 7 speed move everything too much? Or does the cassette spacer not affect the wheel position in the dropout?
