The hubs are the 240 quality we all know of in a 11 speed shimano body. The rim is not the lightest but benefits in stifness. It is stiffer than my wh7850 C24 alloy wheels from shimano. The front wheel is 640g excluded rimtape and QR. and the rear 810.
The new QR are ratlle free. The old ones did make some noise. Still I am using my dura ace qr because in competition they are faster.
