they look good for the price; are they just rebadged novatec? SBC Cycles will be building them onto Kinlin XC279 rims. What spokes, build pattern will make them strong?
Also found few novatecs (old ones I think) on Aliexpress that come in 20/24 but they weigh a LOT.
Easton EC90 XC rims were 20/24... EDIT: Turns out the 26er version is 20h, 29er is 24h
@amey look for cx disc hubs e.g. http://www.edgesportsuk.com/store/index.php/home-page-products/edge-design-cyclocross-disc-hubs-front-rear-20-24h-11speed.html
Or go 40h tandem disc hub and just lace up every other hole...
