Ive built myself some Hope Pro4 DT Swiss XM421 with Super Comp spokes as an experiment in mid weight wheels to see if 25 vs 30 makes a big difference. And the answer is no I can’t really tell the difference on a Maxxis 2.4 tyre.
1790g but most of the ‘additional’ weight over many wheels is at the middle where it only counts towards total system weight, they ride light despite having a couple of hundred g on some of the above and I know that I have a pretty bullet proof trail wheel set that will have no spare parts issues going forward, as long as you keep a couple of spare spokes to hand. You could get the same weight/strength with a 28h build which means 1 spoke length, comp spokes & no hassles.
