Interesting, not that I'm complaining about the shift per se, just the sound. However, how does one go about adjusting camber and toe in/out with an alloy dropout in a carbon frame?
You can do that with the shimano tool (or another that works the same way like the Park Tool, or even a wheel with a 10x1 threaded axle, at a pinch). But with any frame (and especially carbon ones) you need to be sure that the hanger will take the tweak without the frame suffering. To achieve that I would suggest using a solid axle hub (or dummy hub) in the frame with large thick washers bearing against the dropouts, so that the hanger can bend without straining the frame unduly. A QR hub will not shield the dropouts from stress in the same way at all.
http://www.parktool.com/blog/repair-help/rear-derailleur-hanger-alignment shows how to use the park tool gauge but they
a) don't mention the possibility of damaging the frame or protecting it using a solid axle hub and
b) suggest that an equal tolerance exists in both toe in and toe out directions (and similarly camber errors); this is not the case and (IIRC) is not what shimano say, either.
