Bought these a couple of months back and have literally only done 100 miles. An amazing wheelset but I simply prefer my alloy rims instead.
They are 27.5 and are boost front and rear.
The rims are immaculate and so are the hubs. They come with torque caps for the front too. The rear bearings are very slightly rough but are no where near replacement time yet.
XD Rear Freehub.
Tyrewiz included too.
Will ship for free.
