Does anyone know the inner width measurement of the DT Swiss X470 rims? DT Swiss doesn't have it on their website.

TIA

Edit:
The tech specs pdf file at DT Swiss says this rim has an ETRTO of 622 x 18. Does this second number ("18") refer to the inner width?

Edit-edit:
Just remembered Wikipedia is my friend...:rolleyes:

Rims are designated by their nominal rim diameter and their nominal width, separated by a cross (×). Both are measured in millimeters. The rim type codes SS or HB precede the rim designation, whereas code C is appended to the nominal width. Examples:

SS 400×20, HB 422×25, 620×13C

The nominal width of a rim is the inner width between the straight sides or beads as one can easily measure it with a caliper (see the standard for drawings and exact measurement procedures).

The standard widths of straight-side rims are:

18, 20, 22, 24, 27, 30.5

- from Wikipedia

Do I understand this entry correctly, that the "18" in the ETRTO mentioned above is indeed the inner width? Please correct me (and Wikipedia) if I misunderstood.

Nobody wanted to chime in, so I went ahead and bought the rim.

FTW, actual measurements are as follows:

DT Swiss X470 rim:
Inner width - ~18.5mm
Outer width - 24mm
Height - ~17.5mm

...all taken with a simple (analog) plastic caliper.
