Before going further out on a limb I thought it wise to check the Am. Classic web site for wheel building specifications. Here is the chart they provide: http://www.amclassic.com/documents/m...ifications.pdf

If you take a look at this, you will see that there are lower tensions and higher tensions recommended, but the variance has to do solely with the type of rim used, i.e. aluminum alloy and magnesium have higher tensions than carbon. That is due to the differences in rim material strength. True, the front tensions do top out a little lower than I use, at 110 kgf, but that maximum recommendation is higher than reported in this thread for CK R45s and DT 180s.
