Maintainence Simplicity
I’m a framebuilder and also do all of my own wheel builds. If you want a hub that’s maintainable, easily upgradable, and makes a nice buzz, you can’t beat CK. I just had to swap out an XDR driveshell and axle on a 12/142 disc hub that needed straight Shimano 11 speed. It took me 10 minutes using one tool. The hub spins as friction-free as you can imagine. I tuned the bearing preloads just before a race 2 days later in 2 minutes. It would be absurd to accept the limitations of 32 holes only and pointless to compare hub weights with any hub (I9 is terrific, too) that you could buy in 28, 24, etc.
