And I am looking at the SunRingle Rhyno Lite rims they are 27.5 width. The Jalco rims on the nano are 22.2 there should be plenty of room for this rim to work laced to either a 100mm front and 130mm rear Tiagra hub.
I was also looking at the SunRingle CR-18 406 20 inch rims but after scouring the internet for info and reviews of both rims I believe the Rhyno lites to be a bit better quality rim. I am not trying to slight the CR-18's but judging from reviews about the Rhyno Lites strength and ability to stay true it just seems they are a little bit better although a tiny but heavier.
From the listing pictures does anyone see any reason these rims won't work for the Nano?
