@northersouth respectfully I doubt that weight is accurate. The list weight of the lighter centre lock set is 1971g. My 240s exp on the same rim with lighter spokes come in at 1872g and those hubs are a fair bit lighter.
The list weight of them is 1895g? DT are usually pretty much spot on when it comes to their wheel system weights in my experience.
Bear in mind they are 28H wheelset.
As for their durability, the hubs are pretty much bomb proof, the rims I would say have been probably the most reliable I have ever used. I built a set in 2017 which had 3 years of racing on them, including 6 or 7 EWS’s, a month in Canada & god knows how much other stuff & they looked wrecked, but were still straight, very little in terms of dings & just kept rolling. I ended up putting them on my ebike & used them on it for another 2 years before the back wheel started to crack around the eyelets.
I reckon they probably did 500,000m of descending in total.
Before that, I broke a lot of carbon wheels. So these have been stronger, more reliable, not really any heavier & IMO, they ride better than carbon too.
