Yes, those polished silver CR18's by Sun are a light and strong rim. This 590 ERD rim was designed to run 1-3/8" tires, but doesn't necessarily mean you need to do so. I have recently seen 590erd tires for electric bikes 2" wide on ebay as of late that would fit that 590mm. You may see more in the future of this weird size if electric bikes continue to use the 590 rim. BTW, I have a brand new set of the Sun 590 erd polished/eyeletted rims sitting around you may want to take off my hands? pm me if so..
