T’wife bought a set of the black dragon cx wheels the other day, they seem pretty good value for what looks like it will be £100 with the discount code.: double butted spokes, brass nipples, 28 holes and usual adaptability of the switch hubs. 15mm (inside) rim width so too skinny for 29er but fine for proper cx or road tyres. I didn’t weigh them before fitting tyres etc but seem pretty light for spoke count, chunky mtb hubs and so on… The spoke tensions were all tight and pretty even out of the box, been fine for 100 miles so far. Only drawback i could find was the supplied rim tape is a tiny bit too narrow, so it is a faff getting it to stay put and cover all the spoke holes properly unless you glue it in place.
