I’ve tacoed/pringled my rear ArchEX’d wheel to the point that with spokes removed its no longer round, so I’ve bought a replacement

I thought there was only ever one spec for an Arch EX, it seems not?
The dimensions on the sticker decals however do not match one another, nor stans own website?
Old is 559×19, ERD 540mm
New is 559×21, ERD 542mm
Website is 559×21, ERD 541mm

old rim (same as front one), bought from JRA 2 years ago:

new rim, just bought from JeJ:

Does this mean my spokes (I’ve ordered a new set as they’d had some hammer not tensioned properly/evenly for a while before the taco/pringle) will be the wrong length?

If the old ones are from just after they got rid of the old Arch then maybe they just hadn’t gotten around to updating the whole of their stickers. The Arch EX was always sold as being wider and lower profile than the old Arch (21mm vs 19mm). I seem to remember someone on here having a 26″ Stan’s with measurements for the 29″ version on the sticker.

Pretty sure I read that the stickers are wrong
