Thank you for all of your input. So I was able to obtain a 2mm spacer that I can sandwich with the 2.5mm mavic spacer. One question: the 2mm spacer doesn't have any "teeth" or rivets/grooves, it is simply smooth. In regard to the sandwich combination--is it better to put the smooth 2mm spacer closer to the axle or does it matter. I presume the most sturdy spacer (2.5mm) with the grooves should go on the inside/closest to the axle?
Thanks again.
