I’ve had mine since December, and the bearing are running as smoothly as when I bought them, but if you take the end caps off, the bearings are fairly open, so I can understand if they get worn quickly in really mucky weather.
I’ve got mine tubeless, but even when I did have tubes in they still felt like a wonderfully stiff and light wheelset. There isn’t a huge amount of engagement compared to something like chris king hubs, but it hasn’t bothered me, it’s fine for everyday riding. The straight pull spokes might potentially be a little harder to find and/or true, but they’ve been flawless so far, no noises or movement in the slightest.
Considering the 50% off deal, that was crazy good value for them.
