I have orderd a 30mm and a 35mm Rim (same widtz). Strange enough the 30mm rim is about 5g heavier than the 35mm rim. In total it's well within tolerance. The specified ERD is spot on. I used the dtswiss spoke calculator which gave a perfect match. (I have added PHR Washers without without adding these to the spoke length. Therefore my spokes are on the short side - still perfectly fitting)
Looks like a good product. well made. The E.R.D of the 55mm deep rim is 527mm and not 533mm as displayed in the item description. Don't order your spokes before you receive the rim otherwise you may get spokes that are too long like I did.
