So, unten mal die Antwort des verkäufers, die eben kam. Soll ich mich damit zufrieden geben?

"Thank you for your email. Sorry to hear of the inconvenience caused whilst changing your wheels. Fortunately it is unlikely that
there is anything wrong with your wheel, unfortunately there isn't any thing I can do to stop you needing to adjust your gears every time you change your wheel over. The Zipp wheels are very aerodynamic so there is a chance that they have been taken very slightly over to the left during the design of the wheels but essentially you have been very lucky to have not come across this problem in the past. Most wheels are spaced slightly differently on the axle and will give a different chain line but as you pointed out you can usually adjust this out at the lever, in this case it could be that your current wheels are on the upper limit of the right spacing and the Zipp wheels are spaced left, this would give the impression that there is a spacing issue. Sorry for the inconvenience caused, if you wish to have the wheels checked against the alignment of your frame a local bike shop can do this with a frame alignment tool. Thank you"
