Does it have to be 20mm internal? The Kinlin XRxxT rims are 19mm internal, and there's little not to like about them. The XR31T is pretty much my default choice for alloy rims. I only get other rims due to feeling perverse/wanting a change/crazy bargainz.
So... HED aside, given the Aileron is 20mm internal, what recommendations do you have for more readily available 20mm internal disc rim?
DtSwiss R470db? Hope 20FIVE ? What else would you list alongside those?
