I got a set of Roval Control EL’s recently that weigh less than 1500g, but the flip side to that is that they flex a bit, so not great when doing rocky descents and routes with rocks or roots, but that’s the issue with most wheelsets at this weight, they were half the price you’re looking at, have DT internals, so easily fixable over the likes of crossmax’s.
The wheels i would recommend if you want to spend that money are a set of Industry Nine’s, either the old XC’s, or the new Torch wheelset, i’ve had a set of these for 6 years and they’ve worked well, weigh less than 1500g and don’t deflect badly like other lightweight wheels, the only downside is that they cost a fortune!
