In contrast to the above re the Alex / chosen hubs I have found them pretty poor. The rims seem very soft and don’t shrug off dents very well. And they seem a real faff to get up tubeless ( 3 layers of tape and still wouldn’t go up with a track pump). I have tried maxxis, Schwalbe and Specialised tyres and all seem very baggy on the rim. They haven’t seen much use and a good few spokes ended up loose on the rear needing a re true / tension.
The above said I’m not light and ride as such plus they are on a hardtail but I also don’t ride with silly low pressures either. The hubs seem pretty fair though.
If I were in the same position again I would save up more and get a custom hope / dt Swiss build with WTB rims.
Or if money is an issue maybe a custom shimano / wtb build from crc could be possible for that budget depending on hub size / rim needs. I have had a couple of WTB rims before and they seem good quality and tyres seem to seat well on them.
